0. Introduction
i18n module provides internationalization for initramfs at runtime. It
is intended to be generic across different GNU/Linux distributions.
i18n and keyboard settings are stored in different files among
distributions. To deal with it avoiding hardcoding those differences in
the installation script we handle it by mappings between variables used
by dracut and the ones in the system. Package maintainer is expected to
create those for his/her distribution and it's appreciated to share it
with us, so we can include it in source package.
1. Hostonly vs Generic
If you invoke dracut with '-H' option, i18n module install script will
gather variables values from your configuration files using mappings
provided in "/etc/dracut.conf.d/<foo>.conf". Those variables will be
put in "etc/vconsole.conf" and "etc/locale.conf" files inside initramfs
image. Next it will install only declared font, keymaps and so.
When building generic image (dracut without '-H' option), install script
copies all content of directories: consolefonts, consoletrans, unimaps
and keymaps to image. Take into account that's about 4 MiB.
2. Configuration
2.1. Variables
The following variables are used by i18n install script and at initramfs
runtime:
KEYMAP - keyboard translation table loaded by loadkeys
KEYTABLE - base name for keyboard translation table; if UNICODE is
true, Unicode version will be loaded. Overrides KEYMAP.
EXT_KEYMAPS - list of extra keymaps to bo loaded (sep. by space)
UNICODE - boolean, indicating UTF-8 mode
FONT - console font
FONT_MAP - see description of '-m' parameter in setfont manual
FONT_UNIMAP - see description of '-u' parameter in setfont manual
The following are appended to EXT_KEYMAPS only during build time:
UNIKEYMAP
GRP_TOGGLE
They were used in 10redhat-i18n module, but not sure of its purpose.
I'm leaving it in case... The following are taken from the environment:
LANG
LC_ALL
If UNICODE variable is not provided, script indicates if UTF-8 should be
used on the basis of LANG value (if it ends with ".utf8" or similar).
2.2. Setting up mappings
Mappings between variables listed in 2.1. and the ones spread around
your system are set up in /etc/dracut.conf.d/<foo>.conf. You need to
assign mappings to i18n_vars. Here's an example:
i18n_vars="/etc/conf.d/keymaps:KEYMAP,EXTENDED_KEYMAPS-EXT_KEYMAPS /etc/conf.d/consolefont:CONSOLEFONT-FONT,CONSOLETRANSLATION-FONT_MAP /etc/rc.conf:UNICODE"
First we've got name of file in host file system tree. After colon
there's mapping: <from>-<to>. If both variables have the same name you
can enter just a single, but it's important to specify it! The module
will source only variables you've listed.
Below there's detailed description in BNF:
<list> ::= <element> | <element> " " <list>
<element> ::= <conf-file-name> ":" <map-list>
<map-list> ::= <mapping> | <mapping> "," <map-list>
<mapping> ::= <src-var> "-" <dst-var> | <src-var>
We assume no whitespace are allowed between symbols.
<conf-file-name> is a file holding <src-var> in your system.
<src-var> is a variable holding value of meaning the same as <dst-var>.
<dst-var> is a variable which will be set up inside initramfs.
If <dst-var> has the same name as <src-var> we can omit <dst-var>.
Example:
/etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<list> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<element> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<conf-file-name> = /etc/conf.d/keymaps
<map-list> = KEYMAP,extended_keymaps-EXT_KEYMAPS
<mapping> = KEYMAP
<src-var> = KEYMAP
<mapping> = extended_keymaps-EXT_KEYMAPS
<src-var> = extended_keymaps
<dst-var> = EXT_KEYMAPS
2.3. Additional settings
If you encounter following error message: "Directories consolefonts,
consoletrans, keymaps, unimaps not found.", you can provide path where
those directories lie in your system by setting kbddir in configuration
file (the same where you put mappings).
3. Kernel parameters
If you create generic initramfs you can set up i18n by kernel
parameters using variables listed in 2.1. (except of UNIKEYMAP
and GRP_TOGGLE) The recommended minimum is: FONT and KEYMAP.

## Preparation
- ensure that the lvm thin pool is big enough
- backup any (most likely /boot and /boot/efi) device with:
```
# mkdir /restoredev
# dev=<device>; umount $dev; dd if="$dev" of=/restoredev/$(systemd-escape -p "$dev"); mount $dev
```
- backup the MBR
```
# dev=<device>; dd if="$dev" of=/restoredev/$(systemd-escape -p "$dev") bs=446 count=1
# ls -l /dev/disk/by-path/virtio-pci-0000\:00\:07.0
lrwxrwxrwx. 1 root root 9 Jul 24 04:27 /dev/disk/by-path/virtio-pci-0000:00:07.0 -> ../../vda
```
- backup some partitions
```
# dev=/dev/disk/by-path/virtio-pci-0000:00:07.0
# dd if="$dev" of=/restoredev/$(systemd-escape -p "$dev") bs=446 count=1
# umount /boot/efi
# dev=/dev/disk/by-partuuid/687177a8-86b3-4e37-a328-91d20db9563c
# dd if="$dev" of=/restoredev/$(systemd-escape -p "$dev")
# umount /boot
# dev=/dev/disk/by-partuuid/4fdf99e9-4f28-4207-a26f-c76546824eaf

- make a thin snapshot
```
# lvm lvcreate -pr -s rhel/root --name reset
```
- mark the snapshot with a tag
```
# lvm lvchange --addtag reset rhel/reset
```
- remove /restoredev
```
# rm -fr /restoredev
```
## Operation
If a boot entry with ```rd.lvm.mergetags=<tag>``` is selected and there are LVs with ```<tag>```
dracut will
- make a copy of the snapshot
- merge it back to the original
- rename the copy back to the name of the snapshot
- if /restordev appears in the root, then it will restore the images
found in that directory. This can be used to restore /boot and /boot/efi and the
MBR of the boot device

modules.d/91crypt-gpg/READMEnu �[��� # Directions for changing a system from password-based gpg keyfile
# to smartcard-based gpg keyfile
# Be sure that you meet the following requirements:
# 1. GnuPG >= 2.1 installed with
# * Smartcard support enabled (scdaemon must be built)
# * Direct CCID access built into scdaemon
# 2. A password-based gpg keyfile ${KEYFILE} (e.g. "keyfile.gpg"):
# That is, a file containing the slot key for LUKS, which
# has been encrypted symmetrically with GnuPG using
# a password.
# 3. Your public OpenPGP identity ${RECIPIENT} (e.g. "3A696356")
# 4. An OpenPGP smartcard holding the decryption key associated
# with your public identity
# 5. A CCID smartcard reader
# Notes: Requirement 4. and 5. can of course be one device, e.g.
# a USB token with an integrated OpenPGP smartcard
# Make a backup of your keyfile (assuming it lies on the boot partition)
$ cp /boot/${KEYFILE} /safe/place/keyfile.bak.gpg
# Change your keyfile from purely password-based to both
# password-based and key-based (you can then decrypt the keyfile
# with either method). As an example aes256 is chosen, the cipher
# is not important to this guide, but do note that your kernel
# must support it at boot time (be it built into the kernel image
# or loaded as a module from the initramfs).
$ cat /safe/place/keyfile.bak.gpg | gpg -d | gpg --encrypt --recipient ${RECIPIENT} --cipher-algo aes256 --armor -c > /safe/place/keyfile_sc.gpg
# Verify that you can decrypt your new keyfile both with the password
# and your smartcard.
# (with smartcard inserted, you should be prompted for your PIN, unless
# you already did so and have not yet timed out)
$ gpg -d /safe/place/keyfile_sc.gpg
# (with smartcard disconnected, you should be prompted for your password)
$ gpg -d /safe/place/keyfile_sc.gpg
# After verification, replace your old keyfile with your new one
$ su -c 'cp /safe/place/keyfile_sc.gpg /boot/${KEYFILE}'
# Export your public key to where crypt-gpg can find it
$ gpg --armor --export-options export-minimal --export ${RECIPIENT} > /safe/place/crypt-public-key.gpg
$ su -c 'cp /safe/place/crypt-public-key.gpg /etc/dracut.conf.d/crypt-public-key.gpg'
# Rebuild your initramfs as usual
# When booting with any of the requirements not met, crypt-gpg will default to password-based keyfile unlocking.
# If all requirements are met and smartcard support is not disabled by setting the kernel option "rd.luks.smartcard=0"
# crypt-gpg will try find and use a connected OpenPGP smartcard by prompting you for the PIN and then
# unlocking the gpg keyfile with the smartcard.

dracut-shutdown.service - unpack the initramfs to /run/initramfs
SYNOPSIS
--------
dracut-shutdown.service
DESCRIPTION
-----------
This service unpacks the initramfs image to /run/initramfs.
systemd pivots into /run/initramfs at shutdown, so the root filesystem
can be safely unmounted.
The following steps are executed during a shutdown:
* systemd switches to the shutdown.target
* systemd starts /lib/systemd/system/shutdown.target.wants/dracut-shutdown.service
* dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore which unpacks the initramfs to /run/initramfs
* systemd finishes shutdown.target
* systemd kills all processes
* systemd tries to unmount everything and mounts the remaining read-only
* systemd checks, if there is a /run/initramfs/shutdown executable
* if yes, it does a pivot_root to /run/initramfs and executes ./shutdown. The old root is then mounted on /oldroot. /usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable.
* shutdown will try to umount every /oldroot mount and calls the various shutdown hooks from the dracut modules
This ensures, that all devices are disassembled and unmounted cleanly.
To debug the shutdown process, you can get a shell in the shutdown procedure
by injecting "rd.break=pre-shutdown rd.shell" or "rd.break=shutdown rd.shell".
----
# mkdir -p /run/initramfs/etc/cmdline.d
# echo "rd.break=pre-shutdown rd.shell" > /run/initramfs/etc/cmdline.d/debug.conf
# touch /run/initramfs/.need_shutdown
----
In case the unpack of the initramfs fails, dracut-shutdown-onfailure.service
executes to make sure switch root doesn't happen, since it would result in
switching to an incomplete initramfs.

PK ��\#��Q' ' modules.d/98ecryptfs/READMEnu �[��� # Directions for creating the encrypted key that will be used to mount an
# eCryptfs filesystem
# Create the eCryptfs key (encrypted key type)
#
# The encrypted key type supports two formats: the 'default' format allows
# to generate a random symmetric key of the length specified, the 'ecryptfs'
# format generates an authentication token for the eCryptfs filesystem,
# which contains a randomly generated key. Two requirements for the latter
# format is that the key description must contain exactly 16 hexadecimal
# characters and that the encrypted key length must be equal to 64.
$ keyctl add encrypted 1000100010001000 "new ecryptfs trusted:kmk-trusted 64" @u
782117972
# Save the encrypted key
$ su -c 'keyctl pipe `keyctl search @u encrypted 1000100010001000` > /etc/keys/ecryptfs-trusted.blob'
# The eCryptfs key path name can be set in one of the following ways (specified in
# the order in which the variable is overwritten):
1) use the default value:
--------------------------------------------------------------------------
ECRYPTFSKEY="/etc/keys/ecryptfs-trusted.blob"
--------------------------------------------------------------------------
2) create the configuration file '/etc/sysconfig/ecryptfs' and set the ECRYPTFSKEY
variable;
3) specify the eCryptfs key path name in the 'ecryptfskey=' parameter of the kernel command
line.
# The configuration file '/etc/sysconfig/ecryptfs' is also used to specify
# more options for mounting the eCryptfs filesystem:
ECRYPTFSSRCDIR: existent directory in the lower root filesystem;
ECRYPTFSDSTDIR: mount point directory for the eCryptfs filesystem (the directory must be
created in the root filesystem before rebooting the platform);
ECRYPTFS_EXTRA_MOUNT_OPTS: extra mount options for the eCryptfs filesystem (the 'ecryptfs_sig'
option is automatically added by the dracut script).
# Example of the configuration file:
----------- '/etc/sysconfig/ecryptfs' (with default values) -----------
ECRYPTFS_KEY="/etc/keys/ecryptfs-trusted.blob"
ECRYPTFSSRCDIR="/secret"
ECRYPTFSDSTDIR="${ECRYPTFSSRCDIR}"
ECRYPTFS_EXTRA_MOUNT_OPTS=""
-----------------------------------------------------------------------
# If the variable ECRYPTFSDSTDIR is not specified in the configuration file,
# its value will be equal to that of ECRYPTFSSRCDIR.

�A A modules.d/98syslog/READMEnu �[��� Syslog support for dracut
This module provides syslog functionality in the initrd.
This is especially interesting when complex configuration being
used to provide access to the device the rootfs resides on.
When this module is installed into the ramfs it is triggered by
the udev event from the nic being setup (online).
Then if syslog is configured it is started and will forward all
kernel messages to the given syslog server.
The syslog implementation is detected automatically by finding the
appropriate binary with the following order:
rsyslogd
syslogd
syslog-ng
Then if detected the syslog.conf is generated and syslog is started.
Bootparameters:
syslogserver=ip Where to syslog to
sysloglevel=level What level has to be logged
syslogtype=rsyslog|syslog|syslogng
Don't auto detect syslog but set it

## @brief Logging facility module for dracut both at build- and boot-time.
#
# @section intro Introduction
#
# The logger takes a bit from Log4j philosophy. There are defined 6 logging
# levels:
# - TRACE (6)
# The TRACE Level designates finer-grained informational events than the
# DEBUG.
# - DEBUG (5)
# The DEBUG Level designates fine-grained informational events that are most
# useful to debug an application.
# - INFO (4)
# The INFO level designates informational messages that highlight the
# progress of the application at coarse-grained level.
# - WARN (3)
# The WARN level designates potentially harmful situations.
# - ERROR (2)
# The ERROR level designates error events that might still allow the
# application to continue running.
# - FATAL (1)
# The FATAL level designates very severe error events that will presumably
# lead the application to abort.
# Descriptions are borrowed from Log4j documentation:
# http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html
#
# @section usage Usage
#
# First of all you have to start with dlog_init() function which initializes
# required variables. Don't call any other logging function before that one!
# If you're ready with this, you can use following functions which corresponds
# clearly to levels listed in @ref intro Introduction. Here they are:
# - dtrace()
# - ddebug()
# - dinfo()
# - dwarn()
# - derror()
# - dfatal()
# They take all arguments given as a single message to be logged. See dlog()
# function for details how it works. Note that you shouldn't use dlog() by
# yourself. It's wrapped with above functions.
#
# @see dlog_init() dlog()
#
# @section conf Configuration
#
# Logging is controlled by following global variables:
# - @var stdloglvl - logging level to standard error (console output)
# - @var sysloglvl - logging level to syslog (by logger command)
# - @var fileloglvl - logging level to file
# - @var kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
# - @var logfile - log file which is used when @var fileloglvl is higher
# than 0
# and two global variables: @var maxloglvl and @var syslogfacility which <b>must
# not</b> be overwritten. Both are set by dlog_init(). @var maxloglvl holds
# maximum logging level of those three and indicates that dlog_init() was run.
# @var syslogfacility is set either to 'user' (when building initramfs) or
# 'daemon' (when booting).
#
# Logging level set by the variable means that messages from this logging level
# and above (FATAL is the highest) will be shown. Logging levels may be set
# independently for each destination (stderr, syslog, file, kmsg).
#
# @see dlog_init()
## @brief Initializes dracut Logger.
#
# @retval 1 if something has gone wrong
# @retval 0 on success.
#
# @note This function need to be called before any other from this file.
#
# If any of the variables is not set, this function set it to default:
# - @var stdloglvl = 4 (info)
# - @var sysloglvl = 0 (no logging)
# - @var fileloglvl is set to 4 when @var logfile is set too, otherwise it's
# - @var kmsgloglvl = 0 (no logging)
# set to 0
#
# @warning Function sets global variables @var maxloglvl and @syslogfacility.
# See file doc comment for details.

PK 7��\�y;�� � HACKINGnu �[��� Right now, most of the testing is done using a qemu/kvm guest and
generating the initramfs on another box but the support is all present
to build for the "running" machine. For the former, you can boot the guest
using qemu's -kernel and -initrd options.
dracut exists and will build an image. It is command-line equivalent
to most mkinitrd implementations and should be pretty straight-forward
to use.
To use, just run dracut with an output file name and, optionally, a
kernel version (it defaults to using the current). The appropriate
modules will be copied over and things should be good to go. If you'd
like to customize the list of modules copied in, edit /etc/dracut.conf
and set
dracutmodules="foo bar baz"
Note that dracut calls functional components in modules.d "modules"
while kernel modules are called "drivers".
Requirements:
* udev
* nfs module: nfs daemon and rpc helper
* iscsi: iscsi
PK 7��\�I�~� ~� NEWSnu �[��� dracut-049
==========
lsinitrd:
- record loaded kernel modules when hostonly mode is enabled
lsinitrd $image -f */lib/dracut/loaded-kernel-modules.txt
- allow to only unpack certain files
kernel-modules:
- add gpio and pinctrl drivers for arm*/aarch64
- add nfit
kernel-network-modules:
- add vlan kernel modules
ifcfg/write-ifcfg.sh:
- aggregate resolv.conf
livenet:
- Enable OverlayFS overlay in sysroot.mount generator.
dmsquash-live:
- Support a flattened squashfs.img
dracut-systemd:
- Start systemd-vconsole-setup before dracut-cmdline-ask
iscsi:
- do not install all of /etc/iscsi unless hostonly
- start iscsid even w/o systemd
multipath:
- fixed shutdown
network:
- configure NetworkManager to use dhclient
mdraid:
- fixed uuid handling ":" versus "-"
stratis:
- Add additional binaries
new modules:
- 00warpclock
- 99squash
Adds support for building a squashed initramfs
- 35network-legacy
the old 40network
- 35network-manager
alternative to 35network-legacy
- 90kernel-modules-extra
adds out-of-tree kernel modules
testsuite:
- now runs on travis
- support new qemu device options
- even runs without kvm now
dracut-048
==========
dracut.sh:
- fixed finding of btrfs devices
- harden dracut against BASH_ENV environment variable
- no more prelinking
- scan and install "external" kernel modules
- fixed instmods with zero input
- rdsosreport: best effort to strip out passwords
- introduce tri-state hostonly mode
Add a new option --hostonly-mode which accept an <mode> parameter, so we have a tri-state hostonly mode:
* generic: by passing "--no-hostonly" or not passing anything.
"--hostonly-mode" has no effect in such case.
* sloppy: by passing "--hostonly --hostonly-mode sloppy". This
is also the default mode when only "--hostonly" is given.
* strict: by passing "--hostonly --hostonly-mode strict".
Sloppy mode is the original hostonly mode, the new introduced strict
mode will allow modules to ignore more drivers or do some extra job to
save memory and disk space, while making the image less portable.
Also introduced a helper function "optional_hostonly" to make it
easier for modules to leverage new hostonly mode.
To force install modules only in sloppy hostonly mode, use the form:
hostonly="$(optional_hostonly)" instmods <modules>
dracut-install:
- don't error out, if no modules were installed
- support modules.softdep
lsinitrd.sh:
- fixed zstd file signature
kernel:
- include all pci/host modules
- add mmc/core for arm
- Include Intel Volume Management Device support
plymouth:
- fix detection of plymouth directory
drm:
- make failing installation of drm modules nonfatal
- include virtio DRM drivers in hostonly initramfs
stratis:
- initial Stratis support
crypt:
- correct s390 arch to include arch-specific crypto modules
- add cmdline rd.luks.partuuid
- add timeout option rd.luks.timeout
shutdown:
- sleep a little, if a process was killed
network:
- introduce ip=either6 option
iscsi:
- replace iscsistart with iscsid
qeth_rules:
- new module to copy qeth rules
multipath-hostonly:
- merged back into multipath
mdraid:
- fixed case if rd.md.uuid is in ID_FS_UUID format

Important: dracut now requires libkmod for the dracut-install binary helper,
which nows handles kernel module installing and filtering.
dracut.sh:
- restorecon final image file
- fail hard, if we find modules and modules.dep is missing
- support --tmpdir as a relative path
- add default path for --uefi
dracut-functions.sh:
- fix check_vol_slaves() volume group name stripping
dracut-install:
- catch ldd message "cannot execute binary file"
- added kernel module handling with libkmod
Added parameters:
--module,-m
--mod-filter-path, -p
--mod-filter-nopath, -P
--mod-filter-symbol, -s
--mod-filter-nosymbol, -S
--mod-filter-noname, -N
--silent
--kerneldir
--firmwaredirs
- fallback to non-hostonly mode if lsmod fails
lsinitrd:
- new option "--unpack"
- new option "--unpackearly"
- and "--verbose"
general initramfs fixes:
- don't remove 99-cmdline-ask on 'hostonly' cleanup
- call dracut-cmdline-ask.service, if /etc/cmdline.d/*.conf exists
- break at switch_root only for bare rd.break
- add rd.emergency=[reboot|poweroff|halt]
specifies what action to execute in case of a critical failure
- rd.memdebug=4 gives information, about kernel module memory consumption
during loading
dmsquash-live:
- fixed livenet-generator execution flag
and include only, if systemd is used
- fixed dmsquash-live-root.sh for cases where the fstype of the liveimage is squashfs
- fixed typo for rootfs.img
- enable the use of the OverlayFS for the LiveOS root filesystem
Patch notes:
Integrate the option to use an OverlayFS as the root filesystem
into the 90dmsquash-live module for testing purposes.
The rd.live.overlay.overlayfs option allows one to request an
OverlayFS overlay. If a persistent overlay is detected at the
standard LiveOS path, the overlay & type detected will be used.
Tested primarily with transient, in-RAM overlay boots on vfat-
formatted Live USB devices, with persistent overlay directories
on ext4-formatted Live USB devices, and with embedded, persistent
overlay directories on vfat-formatted devices. (Persistent overlay
directories on a vfat-formatted device must be in an embedded
filesystem that supports the creation of trusted.* extended
attributes, and must provide valid d_type in readdir responses.)
The rd.live.overlay.readonly option, which allows a persistent
overlayfs to be mounted read only through a higher level transient
overlay directory, has been implemented through the multiple lower
layers feature of OverlayFS.
The default transient DM overlay size has been adjusted up to 32 GiB.
This change supports comparison of transient Device-mapper vs.
transient OverlayFS overlay performance. A transient DM overlay
is a sparse file in memory, so this setting does not consume more
RAM for legacy applications. It does permit a user to use all of
the available root filesystem storage, and fails gently when it is
consumed, as the available free root filesystem storage on a typical
LiveOS build is only a few GiB. Thus, when booted on other-
than-small RAM systems, the transient DM overlay should not overflow.
OverlayFS offers the potential to use all of the available free RAM
or all of the available free disc storage (on non-vfat-devices)
in its overlay, even beyond the root filesystem available space,
because the OverlayFS root filesystem is a union of directories on
two different partitions.
This patch also cleans up some message spew at shutdown, shortens
the execution path in a couple of places, and uses persistent
DM targets where required.

- add --online option to initqueue
qemu:
- fixed virtual machine detection
lvm:
- remove all quirk arguments for lvm >= 2.2.221
dmsquash:
- fixup for checkisomd5
- increase timeout for checkisomd5
- use non-persistent metadata snapshots for transient overlays.
- overflow support for persistent snapshot.
- use non-persistent metadata snapshots.
- avoid an overlay for persistent, uncompressed, read-write live installations.
multipath:
- multipath.conf included in hostonly mode
- install all multipath path selector kernel modules
iSCSI:
- use the iBFT initiator name, if found and set
- iscsid now present in the initramfs
- iscsistart is done with systemd-run asynchrone to do things in
paralllel. Also restarted for every new interface which shows up.
- If rd.iscsi.waitnet (default) is set, iscsistart is done only
after all interfaces are up.
- If not all interfaces are up and rd.iscsi.testroute (default) is set,
the route to a iscsi target IP is checked and skipped, if there is none.
- If all things fail, we issue a "dummy" interface iscsiroot to retry
everything in the initqueue/timeout.
network:
- added DHCP RENEW/REBIND
- IPv4 DHCP lease time now optional (bootp)
- IPv6 nfs parsing
- fixed IPv6 route parsing
- rd.peerdns=0 parameter to disable DHCP nameserver setting
- detect duplicate IPv4 addresses for static addresses

- add options to tweak timeouts
rd.net.dhcp.retry=<cnt>
If this option is set, dracut will try to connect via dhcp
<cnt> times before failing. Default is 1.
rd.net.timeout.dhcp=<arg>
If this option is set, dhclient is called with "-timeout <arg>".
rd.net.timeout.iflink=<seconds>
Wait <seconds> until link shows up. Default is 60 seconds.
rd.net.timeout.ifup=<seconds>
Wait <seconds> until link has state "UP". Default is 20 seconds.
rd.net.timeout.route=<seconds>

dracut-043
==========
- add missing dmsquash-generator
dracut-042
==========
- fixed dmsetup shutdown
- new kernel command line option "rd.live.overlay.thin"
This option changes the underlying mechanism for the overlay in the
dmsquash module.
Instead of a plain dm snapshot a dm thin snapshot is used. The advantage
of the thin snapshot is, that the TRIM command is recognized, which
means that at runtime, only the occupied blocks will be claimed from
memory, and freed blocks will really be freed in ram.
- dmsquash: Add squashfs support to rd.live.fsimg
Previously rd.live.fsimg only supported filesystems residing in
(compressed) archives.
Now rd.live.fsimg can also be used when a squashfs image is used.
This is achieved by extracting the rootfs image from the squashfs and
then continue with the default routines for rd.live.fsimg.
- lvm: add support for LVM system id
- split up the systemd dracut module
Basic systemd functionality is in 00systemd now.
Switching root and the initrd.target is in 00systemd-initrd.
Dracut additions to the systemd initrd are in 98dracut-systemd.
- support for creating a UEFI boot executable via argument "--uefi"
With an EFI stub, the kernel, the initramfs and a kernel cmdline can be
glued together to a single UEFI executable, which can be booted by a
UEFI BIOS.
- network: split out kernel-network-modules, now in 90kernel-network-modules
- support for ethernet point-to-point connections configured via DHCP
- kernel-modules: install all HID drivers

dracut-021
==========
- fixed systemd in the initramfs (requires systemd >= 187)
- dracut-install: massive speedup with /var on the same filesystem with COW copy
- dracut-install: moved to /usr/lib/dracut until it becomes a general purpose tool
- new options: "rd.usrmount.ro" and "rd.skipfsck"
- less mount/umount
- apply "ro" on the kernel command line also to /usr
- mount according to fstab, if neither "ro" or "rw" is specified
- skip fsck for xfs and btrfs. remount is enough
- give emergency_shell if /usr mount failed
- dracut now uses getopt:
* options can be position independent now!!
* we can now use --option=<arg>
- added option "--kver=<kernel-version>", and the image location can be omitted
# dracut --kver 3.5.0-0.rc7.git1.2.fc18.x86_64
- dracut.sh: for --include copy also the symbolic links
- man pages: lsinitrd and mkinitrd added
- network: We do not support renaming in the kernel namespace anymore (as udev does
that not anymore). So, if a user wants to use ifname, he has to rename
to a custom namespace. "eth[0-9]+" is not allowed anymore. !!!!!
- resume: moved the resume process to the initqueue.
This should prevent accidently mounting the root file system.
- testsuite: add support for: make V=1 TESTS="01 20 40" check
$ sudo make V=1 clean check
now runs the testsuite in verbose mode
$ sudo make TESTS="01 20 40" clean check
now only runs the 01, 20 and 40 tests.

-i, --imagedir Directory with additional images to add
(default: /boot/dracut/)

will be used to create an additional image
--nooverlay Do not use the overlay directory
--noimagedir Do not use the additional image directory
-h, --help This message
--debug Output debug information of the build process
-v, --verbose Verbose output during the build process
- s390 dasd support
dracut-0.6
==========
- dracut: add --kernel-only and --no-kernel arguments
--kernel-only
only install kernel drivers and firmware files
--no-kernel
do not install kernel drivers and firmware files
All kernel module related install commands moved from "install"
to "installkernel".
For "--kernel-only" all installkernel scripts of the specified
modules are used, regardless of any checks, so that all modules
which might be needed by any dracut generic image are in.
The basic idea is to create two images. One image with the kernel
modules and one without. So if the kernel changes, you only have
to replace one image.
Grub and the kernel can handle multiple images, so grub entry can
look like this:
title Fedora (2.6.29.5-191.fc11.i586)
root (hd0,0)
kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img
initrd-20090722.img
the image provided by the initrd rpm
one old backup version is kept like with the kernel
initrd-kernel-2.6.29.5-191.fc11.i586.img
the image provided by the kernel rpm
initrd-config.img
optional image with local configuration files
- dracut: add --kmoddir directory, where to look for kernel modules
-k, --kmoddir [DIR]
specify the directory, where to look for kernel modules
dracut-0.5
==========
- more generic (all plymouth modules, all keyboards, all console fonts)
- more kernel command line parameters (see also man dracut(8))
- a helper tool, which generates the kernel command line (dracut-gencmdline)
- bridged network boot
- a lot of new command line parameter
dracut-0.4
==========
- bugfixes
- firmware loading support
- new internal queue (initqueue)
initqueue now loops until /dev/root exists or root is mounted
init now has the following points to inject scripts:
/cmdline/*.sh
scripts for command line parsing
/pre-udev/*.sh
scripts to run before udev is started
/pre-trigger/*.sh
scripts to run before the main udev trigger is pulled
/initqueue/*.sh
runs in parallel to the udev trigger
Udev events can add scripts here with /sbin/initqueue.
If /sbin/initqueue is called with the "--onetime" option, the script
will be removed after it was run.
If /initqueue/work is created and udev >= 143 then this loop can
process the jobs in parallel to the udevtrigger.
If the udev queue is empty and no root device is found or no root
filesystem was mounted, the user will be dropped to a shell after
a timeout.
Scripts can remove themselves from the initqueue by "rm $job".
/pre-mount/*.sh
scripts to run before the root filesystem is mounted
NFS is an exception, because it has no device node to be created
and mounts in the udev events
/mount/*.sh
scripts to mount the root filesystem
NFS is an exception, because it has no device node to be created
and mounts in the udev events
If the udev queue is empty and no root device is found or no root
filesystem was mounted, the user will be dropped to a shell after
a timeout.
/pre-pivot/*.sh
scripts to run before the real init is executed and the initramfs
disappears
All processes started before should be killed here.
The behaviour of the dmraid module demonstrates how to use the new
mechanism. If it detects a device which is part of a raidmember from a
udev rule, it installs a job to scan for dmraid devices, if the udev
queue is empty. After a scan, it removes itsself from the queue.
dracut-0.3
==========
- first public version
PK 7��\��� � READMEnu �[��� dracut
------
dracut is an event driven initramfs infrastructure.
dracut (the tool) is used to create an initramfs image by copying tools
and files from an installed system and combining it with the
dracut framework, usually found in /usr/lib/dracut/modules.d.
Unlike existing initramfs's, this is an attempt at having as little as
possible hard-coded into the initramfs as possible. The initramfs has
(basically) one purpose in life -- getting the rootfs mounted so that
we can transition to the real rootfs. This is all driven off of
device availability. Therefore, instead of scripts hard-coded to do
various things, we depend on udev to create device nodes for us and
then when we have the rootfs's device node, we mount and carry on.
This helps to keep the time required in the initramfs as little as
possible so that things like a 5 second boot aren't made impossible as
a result of the very existence of an initramfs. It's likely that
we'll grow some hooks for running arbitrary commands in the flow of
the script, but it's worth trying to resist the urge as much as we can
as hooks are guaranteed to be the path to slow-down.
Most of the initramfs generation functionality in dracut is provided by a bunch
of generator modules that are sourced by the main dracut script to install
specific functionality into the initramfs. They live in the modules.d
subdirectory, and use functionality provided by dracut-functions to do their
work.
Some general rules for writing modules:
* Use one of the inst family of functions to actually install files
on to the initramfs. They handle mangling the pathnames and (for binaries,
scripts, and kernel modules) installing dependencies as appropriate so
you do not have to.
* Scripts that end up on the initramfs should be POSIX compliant. dracut
will try to use /bin/dash as /bin/sh for the initramfs if it is available,
so you should install it on your system -- dash aims for strict POSIX
compliance to the extent possible.
* Hooks MUST be POSIX compliant -- they are sourced by the init script,
and having a bashism break your user's ability to boot really sucks.
* Generator modules should have a two digit numeric prefix -- they run in
ascending sort order. Anything in the 90-99 range is stuff that dracut
relies on, so try not to break those hooks.
* Hooks must have a .sh extension.
* Generator modules are described in more detail in README.modules.
* We have some breakpoints for debugging your hooks. If you pass 'rdbreak'
as a kernel parameter, the initramfs will drop to a shell just before
switching to a new root. You can pass 'rdbreak=hookpoint', and the initramfs
will break just before hooks in that hookpoint run.
Also, there is an attempt to keep things as distribution-agnostic as
possible. Every distribution has their own tool here and it's not
something which is really interesting to have separate across them.
So contributions to help decrease the distro-dependencies are welcome.
Currently dracut lives on github.com and kernel.org.

PK 7��\��}~� � TODOnu �[��� Current TODO list, broken into things which are relevant for the
initramfs itself (/init et al) vs the generator.
A lot of things are/should be marked with "FIXME" in the code.
Items are ordered in priority.
INITRAMFS TODO
- search domain string
- allow dual stack configuration (IPv4, IPv6) for the same interface
- "bind-mount" kernel drivers in real root for the rescue image,
if the real root does not have any kernel modules for this kernel
https://bugzilla.redhat.com/show_bug.cgi?id=1046510
- use info and warn prefix
- generate systemd unit dracut-initramfs-restore in /run/systemd dynamically
- put "root=" parsing hooks in separate hook dir
- call "root=" parsing hooks after getting new rootpath from dhcp
- put mount hook in main initqueue loop / careful about resume!
- the hard-coded list of udev rules that we care about is kind of lame.
- panic fallback
- progress indication for fsck https://bugzilla.redhat.com/show_bug.cgi?id=827118
- domain, searchdomain https://bugzilla.redhat.com/show_bug.cgi?id=840778
- probably fix "--include" https://bugzilla.redhat.com/show_bug.cgi?id=849338
GENERATOR TODO
- report errors on missing files in check()
- remove wait for swap devs, if no "resume=" is given on the kernel command line
- remove wait for swap devs, if the "resume" dracut module is not included (omitted)
- add presets (predefined set of modules)
- add interpreter/plugin-scripts to be sourced at the beginning or end (can use dracut-functions)
- add mechanism for module specific command line options
- pkg-config integration, to make it easy for other packages to use us.
- default module specification could use some work
- udev rule copying, as mentioned above, is a bit too hard-coded
- dracut-install parse LD_SHOW_AUXV="" AT_PLATFORM for lib install
CODE TODO
- document more functions
- make function vars local, and prefix with "_"
Future Enhancement Requests
- run ssh server to enter crypto password or perform debugging (supported by debian)
- https://bugzilla.redhat.com/show_bug.cgi?id=524727 - dracut + encrypted root + networking
- lsinitrd --print-cmdline
- dracut --print-cmdline error if additional arguments
- library for cmdline

<a class="ulink" href="http://en.wikipedia.org/wiki/Initrd" target="_top">http://en.wikipedia.org/wiki/Initrd</a> which is licensed under the
Creative Commons Attribution/Share-Alike License.</p><div class="chapter"><div class="titlepage"><div><div><h2 class="title"><a id="_definition"></a>Chapter 1. Definition</h2></div></div></div><p>An <span class="emphasis"><em>initial ramdisk</em></span> is a temporary file system used in the boot process of the
Linux kernel. <span class="emphasis"><em>initrd</em></span> and <span class="emphasis"><em>initramfs</em></span> refer to slightly different schemes for
loading this file system into memory. Both are commonly used to make
preparations before the real root file system can be mounted.</p></div><div class="chapter"><div class="titlepage"><div><div><h2 class="title"><a id="_rationale"></a>Chapter 2. Rationale</h2></div></div></div><p>Many Linux distributions ship a single, generic kernel image that is intended to
boot as wide a variety of hardware as possible. The device drivers for this
generic kernel image are included as loadable modules, as it is not possible to
statically compile them all into the one kernel without making it too large to
boot from computers with limited memory or from lower-capacity media like floppy
disks.</p><p>This then raises the problem of detecting and loading the modules necessary to
mount the root file system at boot time (or, for that matter, deducing where or
what the root file system is).</p><p>To further complicate matters, the root file system may be on a software RAID
volume, LVM, NFS (on diskless workstations), or on an encrypted partition. All
of these require special preparations to mount.</p><p>Another complication is kernel support for hibernation, which suspends the
computer to disk by dumping an image of the entire system to a swap partition or
a regular file, then powering off. On next boot, this image has to be made
accessible before it can be loaded back into memory.</p><p>To avoid having to hardcode handling for so many special cases into the kernel,
an initial boot stage with a temporary root file system
—now dubbed early user space— is used. This root file system would contain
user-space helpers that would do the hardware detection, module loading and
device discovery necessary to get the real root file system mounted.</p></div><div class="chapter"><div class="titlepage"><div><div><h2 class="title"><a id="_implementation"></a>Chapter 3. Implementation</h2></div></div></div><p>An image of this initial root file system (along with the kernel image) must be
stored somewhere accessible by the Linux bootloader or the boot firmware of the
computer. This can be:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
The root file system itself
</li><li class="listitem">
A boot image on an optical disc
</li><li class="listitem">
A small ext2/ext3 or FAT-formatted partition on a local disk
(a <span class="emphasis"><em>boot partition</em></span>)
</li><li class="listitem">
A TFTP server (on systems that can boot from Ethernet)
</li></ul></div><p>The bootloader will load the kernel and initial root file system image into
memory and then start the kernel, passing in the memory address of the image.</p><p>Depending on which algorithms were compiled statically into it, the kernel can
currently unpack initrd/initramfs images compressed with gzip, bzip2 and LZMA.</p></div><div class="chapter"><div class="titlepage"><div><div><h2 class="title"><a id="_mount_preparations"></a>Chapter 4. Mount preparations</h2></div></div></div><p>dracut can generate a customized initrams image which contains only whatever is
necessary to boot some particular computer, such as ATA, SCSI and filesystem
kernel modules (host-only mode).</p><p>dracut can also generate a more generic initramfs image (default mode).</p><p>dracut’s initramfs starts only with the device name of the root file system (or
its UUID) and must discover everything else at boot time. A complex cascade of
tasks must be performed to get the root file system mounted:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
Any hardware drivers that the boot process depends on must be loaded. All
kernel modules for common storage devices are packed onto the initramfs and then
udev pulls in modules matching the computer’s detected hardware.
</li><li class="listitem">
On systems which display a boot rd.splash screen, the video hardware must be
initialized and a user-space helper started to paint animations onto the display
in lockstep with the boot process.
</li><li class="listitem"><p class="simpara">
If the root file system is on NFS, dracut does then:
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem">
Bring up the primary network interface.
</li><li class="listitem">
Invoke a DHCP client, with which it can obtain a DHCP lease.
</li><li class="listitem">
Extract the name of the NFS share and the address of the NFS server from the
lease.
</li><li class="listitem">
Mount the NFS share.
</li></ul></div></li><li class="listitem">
If the root file system appears to be on a software RAID device, there is no
way of knowing which devices the RAID volume spans; the standard MD utilities
must be invoked to scan all available block devices with a raid signature and
bring the required ones online.
</li><li class="listitem">
If the root file system appears to be on a logical volume, the LVM utilities
must be invoked to scan for and activate the volume group containing it.
</li><li class="listitem"><p class="simpara">
If the root file system is on an encrypted block device:
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem">
Invoke a helper script to prompt the user to type in a passphrase and/or
insert a hardware token (such as a smart card or a USB security dongle).
</li></ul></div></li><li class="listitem">
Create a decryption target with the device mapper.
</li></ul></div><p>dracut uses udev, an event-driven hotplug agent, which invokes helper programs
as hardware devices, disk partitions and storage volumes matching certain rules
come online. This allows discovery to run in parallel, and to progressively
cascade into arbitrary nestings of LVM, RAID or encryption to get at the root
file system.</p><p>When the root file system finally becomes visible:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
Any maintenance tasks which cannot run on a mounted root file system
are done.
</li><li class="listitem">
The root file system is mounted read-only.
</li><li class="listitem">
Any processes which must continue running (such as the rd.splash screen helper
and its command FIFO) are hoisted into the newly-mounted root file system.
</li></ul></div><p>The final root file system cannot simply be mounted over /, since that would
make the scripts and tools on the initial root file system inaccessible for any
final cleanup tasks. On an initramfs, the initial root file system cannot be
rotated away. Instead, it is simply emptied and the final root file system
mounted over the top.</p><p>If the systemd module is used in the initramfs, the ordering of the services
started looks like <a class="xref" href="#dracutbootup7" title="Chapter 13. DRACUT.BOOTUP(7)">Chapter 13, <em>DRACUT.BOOTUP(7)</em></a>.</p></div><div class="chapter"><div class="titlepage"><div><div><h2 class="title"><a id="_dracut_on_shutdown"></a>Chapter 5. Dracut on shutdown</h2></div></div></div><p>On a systemd driven system, the dracut initramfs is also used for the shutdown
procedure.</p><p>The following steps are executed during a shutdown:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
systemd switches to the shutdown.target
</li><li class="listitem">
systemd starts
$prefix/lib/systemd/system/shutdown.target.wants/dracut-shutdown.service
</li><li class="listitem">
dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore
which unpacks the initramfs to /run/initramfs
</li><li class="listitem">
systemd finishes shutdown.target
</li><li class="listitem">
systemd kills all processes
</li><li class="listitem">
systemd tries to unmount everything and mounts the remaining read-only
</li><li class="listitem">
systemd checks, if there is a /run/initramfs/shutdown executable
</li><li class="listitem">
if yes, it does a pivot_root to /run/initramfs and executes ./shutdown.
The old root is then mounted on /oldroot.
/usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable.
</li><li class="listitem">
shutdown will try to umount every /oldroot mount and calls the various
shutdown hooks from the dracut modules
</li></ul></div><p>This ensures, that all devices are disassembled and unmounted cleanly.</p></div></div><div class="part"><div class="titlepage"><div><div><h1 class="title"><a id="_user_manual"></a>Part II.

If <kernel version> is omitted, then the version of the actual running
kernel is used. If <image> is omitted or empty, then the default location
/boot/initramfs-<kernel version>.img is used.</p><p>dracut creates an initial image used by the kernel for preloading the block
device modules (such as IDE, SCSI or RAID) which are needed to access the root
filesystem, mounting the root filesystem and booting into the real system.</p><p>At boot time, the kernel unpacks that archive into RAM disk, mounts and uses it
as initial root file system. All finding of the root device happens in this
early userspace.</p><p>Initramfs images are also called "initrd".</p><p>For a complete list of kernel command line options see <span class="strong"><strong>dracut.cmdline</strong></span>(7).</p><p>If you are dropped to an emergency shell, while booting your initramfs,
the file <span class="emphasis"><em>/run/initramfs/rdsosreport.txt</em></span> is created, which can be saved to a
(to be mounted by hand) partition (usually /boot) or a USB stick.
Additional debugging info can be produced by adding <span class="strong"><strong>rd.debug</strong></span> to the kernel
command line. <span class="emphasis"><em>/run/initramfs/rdsosreport.txt</em></span> contains all logs and the output
of some tools. It should be attached to any report about dracut problems.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_usage"></a>USAGE</h2></div></div></div><p>To create a initramfs image, the most simple command is:</p><pre class="screen"># dracut</pre><p>This will generate a general purpose initramfs image, with all possible
functionality resulting of the combination of the installed dracut modules and
system tools. The image is /boot/initramfs-<span class="emphasis"><em><code class="literal"><kernel version></code></em></span>.img and
contains the kernel modules of the currently active kernel with version
<span class="emphasis"><em><code class="literal"><kernel version></code></em></span>.</p><p>If the initramfs image already exists, dracut will display an error message, and
to overwrite the existing image, you have to use the --force option.</p><pre class="screen"># dracut --force</pre><p>If you want to specify another filename for the resulting image you would issue
a command like:</p><pre class="screen"># dracut foobar.img</pre><p>To generate an image for a specific kernel version, the command would be:</p><pre class="screen"># dracut foobar.img 2.6.40-1.rc5.f20</pre><p>A shortcut to generate the image at the default location for a specific kernel
version is:</p><pre class="screen"># dracut --kver 2.6.40-1.rc5.f20</pre><p>If you want to create lighter, smaller initramfs images, you may want to specify
the --hostonly or -H option. Using this option, the resulting image will
contain only those dracut modules, kernel modules and filesystems, which are
needed to boot this specific machine. This has the drawback, that you can’t put
the disk on another controller or machine, and that you can’t switch to another
root filesystem, without recreating the initramfs image. The usage of the
--hostonly option is only for experts and you will have to keep the broken
pieces. At least keep a copy of a general purpose image (and corresponding
kernel) as a fallback to rescue your system.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_inspecting_the_contents"></a>Inspecting the Contents</h3></div></div></div><p>To see the contents of the image created by dracut, you can use the lsinitrd
tool.</p><pre class="screen"># lsinitrd | less</pre><p>To display the contents of a file in the initramfs also use the lsinitrd tool:</p><pre class="screen"># lsinitrd -f /etc/ld.so.conf
include ld.so.conf.d/*.conf</pre></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_adding_dracut_modules"></a>Adding dracut Modules</h3></div></div></div><p>Some dracut modules are turned off by default and have to be activated manually.
You can do this by adding the dracut modules to the configuration file
<span class="emphasis"><em>/etc/dracut.conf</em></span> or <span class="emphasis"><em>/etc/dracut.conf.d/myconf.conf</em></span>. See <span class="strong"><strong>dracut.conf</strong></span>(5).
You can also add dracut modules on the command line
by using the -a or --add option:</p><pre class="screen"># dracut --add bootchart initramfs-bootchart.img</pre><p>To see a list of available dracut modules, use the --list-modules option:</p><pre class="screen"># dracut --list-modules</pre></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_omitting_dracut_modules"></a>Omitting dracut Modules</h3></div></div></div><p>Sometimes you don’t want a dracut module to be included for reasons of speed,
size or functionality. To do this, either specify the omit_dracutmodules
variable in the <span class="emphasis"><em>dracut.conf</em></span> or <span class="emphasis"><em>/etc/dracut.conf.d/myconf.conf</em></span> configuration
file (see <span class="strong"><strong>dracut.conf</strong></span>(5)), or use the -o or --omit option
on the command line:</p><pre class="screen"># dracut -o "multipath lvm" no-multipath-lvm.img</pre></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_adding_kernel_modules"></a>Adding Kernel Modules</h3></div></div></div><p>If you need a special kernel module in the initramfs, which is not
automatically picked up by dracut, you have the use the --add-drivers option
on the command line or the drivers variable in the <span class="emphasis"><em>/etc/dracut.conf</em></span>
or <span class="emphasis"><em>/etc/dracut.conf.d/myconf.conf</em></span> configuration file (see <span class="strong"><strong>dracut.conf</strong></span>(5)):</p><pre class="screen"># dracut --add-drivers mymod initramfs-with-mymod.img</pre></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_boot_parameters"></a>Boot parameters</h3></div></div></div><p>An initramfs generated without the "hostonly" mode, does not contain any system
configuration files (except for some special exceptions), so the configuration
has to be done on the kernel command line. With this flexibility, you can easily
boot from a changed root partition, without the need to recompile the initramfs
image. So, you could completely change your root partition (move it inside a md
raid with encryption and LVM on top), as long as you specify the correct
filesystem LABEL or UUID on the kernel command line for your root device, dracut
will find it and boot from it.</p><p>The kernel command line can also be provided by the dhcp server with the
root-path option. See <a class="xref" href="#NetworkBoot" title="Network Boot">the section called “Network Boot”</a>.</p><p>For a full reference of all kernel command line parameters,
see <span class="strong"><strong>dracut.cmdline</strong></span>(5).</p><p>To get a quick start for the suitable kernel command line on your system,
use the <span class="emphasis"><em>--print-cmdline</em></span> option:</p><pre class="screen"># dracut --print-cmdline
root=UUID=8b8b6f91-95c7-4da2-831b-171e12179081 rootflags=rw,relatime,discard,data=ordered rootfstype=ext4</pre><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_specifying_the_root_device"></a>Specifying the root Device</h4></div></div></div><p>This is the only option dracut really needs to boot from your root partition.
Because your root partition can live in various environments, there are a lot of
formats for the root= option. The most basic one is root=<span class="emphasis"><em><code class="literal"><path to device
node></code></em></span>:</p><pre class="screen">root=/dev/sda2</pre><p>Because device node names can change, dependent on the drive ordering, you are
encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL)
to specify your root partition:</p><pre class="screen">root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331</pre><p>or</p><pre class="screen">root=LABEL=myrootpartitionlabel</pre><p>To see all UUIDs or LABELs on your system, do:</p><pre class="screen"># ls -l /dev/disk/by-uuid</pre><p>or</p><pre class="screen"># ls -l /dev/disk/by-label</pre><p>If your root partition is on the network see <a class="xref" href="#NetworkBoot" title="Network Boot">the section called “Network Boot”</a>.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_keyboard_settings"></a>Keyboard Settings</h4></div></div></div><p>If you have to input passwords for encrypted disk volumes, you might want to set
the keyboard layout and specify a display font.</p><p>A typical german kernel command would contain:</p><pre class="screen">rd.vconsole.font=latarcyrheb-sun16 rd.vconsole.keymap=de-latin1-nodeadkeys rd.locale.LANG=de_DE.UTF-8</pre><p>Setting these options can override the setting stored on your system, if you use
a modern init system, like systemd.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_blacklisting_kernel_modules"></a>Blacklisting Kernel Modules</h4></div></div></div><p>Sometimes it is required to prevent the automatic kernel module loading of a
specific kernel module. To do this, just add rd.blacklist=<span class="emphasis"><em><code class="literal"><kernel module
name></code></em></span>, with <span class="emphasis"><em><code class="literal"><kernel module name></code></em></span> not containing the <span class="emphasis"><em>.ko</em></span>
suffix, to the kernel command line. For example:</p><pre class="screen">rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau</pre><p>The option can be specified multiple times on the kernel command line.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_speeding_up_the_boot_process"></a>Speeding up the Boot Process</h4></div></div></div><p>If you want to speed up the boot process, you can specify as much information
for dracut on the kernel command as possible. For example, you can tell dracut,
that you root partition is not on a LVM volume or not on a raid partition, or
that it lives inside a specific crypto LUKS encrypted volume. By default, dracut
searches everywhere. A typical dracut kernel command line for a plain primary or
logical partition would contain:</p><pre class="screen">rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0</pre><p>This turns off every automatic assembly of LVM, MD raids, DM raids and
crypto LUKS.</p><p>Of course, you could also omit the dracut modules in the initramfs creation
process, but then you would lose the possibility to turn it on on demand.</p></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="Injecting"></a>Injecting custom Files</h3></div></div></div><p>To add your own files to the initramfs image, you have several possibilities.</p><p>The --include option let you specify a source path and a target path.
For example</p><pre class="screen"># dracut --include cmdline-preset /etc/cmdline.d/mycmdline.conf initramfs-cmdline-pre.img</pre><p>will create an initramfs image, where the file cmdline-preset will be copied
inside the initramfs to <span class="emphasis"><em>/etc/cmdline.d/mycmdline.conf</em></span>. --include can only
be specified once.</p><pre class="screen"># mkdir -p rd.live.overlay/etc/cmdline.d
# mkdir -p rd.live.overlay/etc/conf.d
# echo "ip=dhcp" >> rd.live.overlay/etc/cmdline.d/mycmdline.conf
# echo export FOO=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# echo export BAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# tree rd.live.overlay/
rd.live.overlay/
`-- etc
|-- cmdline.d
| `-- mycmdline.conf
`-- conf.d
`-- testvar.conf
# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img</pre><p>This will put the contents of the rd.live.overlay directory into the root of the
initramfs image.</p><p>The --install option let you specify several files, which will get installed in
the initramfs image at the same location, as they are present on initramfs
creation time.</p><pre class="screen"># dracut --install 'strace fsck.ext3 ssh' initramfs-dbg.img</pre><p>This will create an initramfs with the strace, fsck.ext3 and ssh executables,
together with the libraries needed to start those. The --install option can be
specified multiple times.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="NetworkBoot"></a>Network Boot</h3></div></div></div><p>If your root partition is on a network drive, you have to have the network
dracut modules installed to create a network aware initramfs image.</p><p>If you specify ip=dhcp on the kernel command line, then dracut asks a dhcp
server about the ip address for the machine. The dhcp server can also serve an
additional root-path, which will set the root device for dracut. With this
mechanism, you have static configuration on your client machine and a
centralized boot configuration on your TFTP/DHCP server. If you can’t pass a
kernel command line, then you can inject <span class="emphasis"><em>/etc/cmdline.d/mycmdline.conf</em></span>, with a
method described in <a class="xref" href="#Injecting" title="Injecting custom Files">the section called “Injecting custom Files”</a>.</p><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_reducing_the_image_size"></a>Reducing the Image Size</h4></div></div></div><p>To reduce the size of the initramfs, you should create it with by omitting all
dracut modules, which you know, you don’t need to boot the machine.</p><p>You can also specify the exact dracut and kernel modules to produce a very tiny
initramfs image.</p><p>For example for a NFS image, you would do:</p><pre class="screen"># dracut -m "nfs network base" initramfs-nfs-only.img</pre><p>Then you would boot from this image with your target machine and reduce the size
once more by creating it on the target machine with the --host-only option:</p><pre class="screen"># dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img</pre><p>This will reduce the size of the initramfs image significantly.</p></div></div></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_troubleshooting"></a>Troubleshooting</h2></div></div></div><p>If the boot process does not succeed, you have several options to debug the
situation. Some of the basic operations are covered here. For more information

encouraged. The root device should better be identified by LABEL or UUID. If a
label is used, as in <span class="emphasis"><em>root=LABEL=<label_of_root></em></span> the initramfs will search all

with that UUID as the root filesystem.</p><p>In the following all kernel command line parameters, which are processed by
dracut, are described.</p><p>"rd.*" parameters mentioned without "=" are boolean parameters. They can be
turned on/off by setting them to {0|1}. If the assignment with "=" is missing
"=1" is implied. For example <span class="emphasis"><em>rd.info</em></span> can be turned off with <span class="emphasis"><em>rd.info=0</em></span> or
turned on with <span class="emphasis"><em>rd.info=1</em></span> or <span class="emphasis"><em>rd.info</em></span>. The last value in the kernel command

All
modules are located in <span class="emphasis"><em>/usr/lib/dracut/modules.d</em></span> or in <span class="emphasis"><em><git-src>/modules.d</em></span>.
The most basic dracut module is <span class="emphasis"><em>99base</em></span>. In <span class="emphasis"><em>99base</em></span> the initial shell script
init is defined, which gets run by the kernel after initramfs loading. Although
you can replace init with your own version of <span class="emphasis"><em>99base</em></span>, this is not encouraged.
Instead you should use, if possible, the hooks of dracut. All hooks, and the
point of time in which they are executed, are described in <a class="xref" href="#stages" title="Boot Process Stages">the section called “Boot Process Stages”</a>.</p><p>The main script, which creates the initramfs is dracut itself. It parses all
arguments and sets up the directory, in which everything is installed. It then
executes all check, install, installkernel scripts found in the modules, which
are to be processed. After everything is installed, the install directory is
archived and compressed to the final initramfs image. All helper functions used
by check, install and installkernel are found in in the file <span class="emphasis"><em>dracut-functions</em></span>.
These shell functions are available to all module installer (install,
installkernel) scripts, without the need to source <span class="emphasis"><em>dracut-functions</em></span>.</p><p>A module can check the preconditions for install and installkernel with the
check script. Also dependencies can be expressed with check. If a module passed
check, install and installkernel will be called to install all of the necessary
files for the module. To split between kernel and non-kernel parts of the
installation, all kernel module related parts have to be in installkernel. All
other files found in a module directory are module specific and mostly are hook
scripts and udev rules.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="stages"></a>Boot Process Stages</h2></div></div></div><p>dracut modules can insert custom script at various points, to control the boot
process.
These hooks are plain directories containing shell scripts ending with ".sh",
which are sourced by init.
Common used functions are in <span class="emphasis"><em>dracut-lib.sh</em></span>, which can be sourced by any script.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_hook_cmdline"></a>Hook: cmdline</h3></div></div></div><p>The <span class="emphasis"><em>cmdline</em></span> hook is a place to insert scripts to parse the kernel command line
and prepare the later actions, like setting up udev rules and configuration
files.</p><p>In this hook the most important environment variable is defined: root. The
second one is rootok, which indicates, that a module claimed to be able to parse
the root defined. So for example, <span class="strong"><strong>root=</strong></span><span class="emphasis"><em>iscsi:….</em></span> will be claimed by the
iscsi dracut module, which then sets rootok.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_hook_pre_udev"></a>Hook: pre-udev</h3></div></div></div><p>This hook is executed right after the cmdline hook and a check if root and
rootok were set. Here modules can take action with the final root, and before
udev has been run.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_start_udev"></a>Start Udev</h3></div></div></div><p>Now udev is started and the logging for udev is setup.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_hook_pre_trigger"></a>Hook: pre-trigger</h3></div></div></div><p>In this hook, you can set udev environment variables with <span class="strong"><strong>udevadm control
--property=KEY=<span class="emphasis"><em>value</em></span></strong></span> or control the further execution of udev with
udevadm.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="_trigger_udev"></a>Trigger Udev</h3></div></div></div><p>udev is triggered by calling udevadm trigger, which sends add events for all

by calling /sbin/initqueue.</p><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_initqueue"></a>Initqueue</h4></div></div></div><p>This hook gets executed every time a script is inserted here, regardless of the
