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

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.

Most of the functionality that dracut implements are actually implemented
by dracut modules. dracut modules live in modules.d, and have the following
structure:
dracut_install_dir/modules.d/
00modname/
module-setup.sh
check
<other files as needed by the hook>
00modname: The name of the module prefixed by a two-digit numeric sort code.
The numeric code must be present and in the range of 00 - 99.
Modules with lower numbers are installed first. This is important
because the dracut install functions (which install files onto
the initrd) refuse to overwrite already installed files. This makes
it easy for an earlier module to override the functionality of a
later module, so that you can have a distro or system specific
module override or modify the functionality of a generic module
without having to patch the more generic module.
module-setup.sh:
dracut sources this script to install the functionality that a
module implements onto the initrd. For the most part, this amounts
to copying files from the host system onto the initrd in a controlled
manner.
install():
This function of module-setup.sh is called to install all
non-kernel files. dracut supplies several install functions that are
specialized for different file types. Browse through dracut-functions
fore more details. dracut also provides a $moddir variable if you
need to install a file from the module directory, such as an initrd
hook, a udev rule, or a specialized executable.
installkernel():
This function of module-setup.sh is called to install all
kernel related files.
check():
dracut calls this function to check and see if a module can be installed
on the initrd.
When called without options, check should check to make sure that
any files it needs to install into the initrd from the host system
are present. It should exit with a 0 if they are, and a 1 if they are
not.
When called with $hostonly set, it should perform the same check
that it would without it set, and it should also check to see if the
functionality the module implements is being used on the host system.
For example, if this module handles installing support for LUKS
encrypted volumes, it should return 0 if all the tools to handle
encrpted volumes are available and the host system has the root
partition on an encrypted volume, 1 otherwise.
depends():
This function should output a list of dracut modules
that it relies upon. An example would be the nfs and iscsi modules,
which rely on the network module to detect and configure network
interfaces.
Any other files in the module will not be touched by dracut directly.
You are encouraged to provide a README that describes what the module is for.
HOOKS
=====
init has the following hook points to inject scripts:
/lib/dracut/hooks/cmdline/*.sh
scripts for command line parsing
/lib/dracut/hooks/pre-udev/*.sh
scripts to run before udev is started
/lib/dracut/hooks/pre-trigger/*.sh
scripts to run before the main udev trigger is pulled
/lib/dracut/hooks/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 /lib/dracut/hooks/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".
/lib/dracut/hooks/pre-mount/*.sh
scripts to run before the root filesystem is mounted
Network filesystems like NFS that do not use device files are an
exception. Root can be mounted already at this point.
/lib/dracut/hooks/mount/*.sh
scripts to mount the root filesystem
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.
/lib/dracut/hooks/pre-pivot/*.sh
scripts to run before latter initramfs cleanups
/lib/dracut/hooks/cleanup/*.sh
scripts to run before the real init is executed and the initramfs
disappears
All processes started before should be killed here.

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

# BASH Notes
## basename
Don't use `basename`, use:
```shell
file=${path##*/}
```
## dirname
Don't use `dirname`, use:
```shell
dir=${path%/*}
```
## shopt
If you set `shopt` in a function, reset to its default state with `trap`:
```shell
func() {
trap "$(shopt -p globstar)" RETURN
shopt -q -s globstar
}
```
## find, grep, print0, -0, -z
Don't use `find` in `for` loops, because filenames can contain spaces.
Try to use `globstar` and `nullglob` or null byte terminated strings.
Instead of:
```shell
func() {
for file in $(find /usr/lib* -type f -name 'lib*.a' -print0 ); do
echo $file
done
}
```
use:
```shell
func() {
trap "$(shopt -p nullglob globstar)" RETURN
shopt -q -s nullglob globstar
for file in /usr/lib*/**/lib*.a; do
[[ -f $file ]] || continue
echo "$file"
done
}
```
Or collect the filenames in an array, if you need them more than once:
```shell
func() {
trap "$(shopt -p globstar)" RETURN
shopt -q -s globstar
filenames=( /usr/lib*/**/lib*.a )
for file in "${filenames[@]}"; do
[[ -f $file ]] || continue
echo "$file"
done
}
```
Or, if you really want to use `find`, use `-print0` and an array:
```shell
func() {
mapfile -t -d '' filenames < <(find /usr/lib* -type f -name 'lib*.a' -print0)
for file in "${filenames[@]}"; do
echo "$file"
done
}
```
Note: `-d ''` is the same as `-d $'\0'` and sets the null byte as the delimiter.
or:
```shell
func() {
find /usr/lib* -type f -name 'lib*.a' -print0 | while read -r -d '' file; do
echo "$file"
done
}
```
or
```shell
func() {
while read -r -d '' file; do
echo "$file"
done < <(find /usr/lib* -type f -name 'lib*.a' -print0)
}
```
Use the tool options for null terminated strings, like `-print0`, `-0`, `-z`, etc.
## prefix or suffix array elements
Instead of:
```shell
func() {
other-cmd $(for k in "$@"; do echo "prefix-$k"; done)
}
```
do
```shell
func() {
other-cmd "${@/#/prefix-}"
}
```
or suffix:
```shell
func() {
other-cmd "${@/%/-suffix}"
}
```
## Join array elements with a separator char
Here we have an associate array `_drivers`, where we want to print the keys separated by ',':
```shell
if [[ ${!_drivers[*]} ]]; then
echo "rd.driver.pre=$(IFS=, ;echo "${!_drivers[*]}")" > "${initdir}"/etc/cmdline.d/00-watchdog.conf
fi
```
## Optional parameters to commands
If you want to call a command `cmd` with an option, if a variable is set, rather than doing:
```shell
func() {
local param="$1"
if [[ $param ]]; then
param="--this-special-option $param"
fi
cmd $param
}
```
do it like this:
```shell
func() {
local param="$1"
cmd ${param:+--this-special-option "$param"}
}
# cmd --this-special-option 'abc'
func 'abc'
# cmd
func ''
# cmd
func
```
If you want to specify the option even with an empty string do this:
```shell
func() {
local -a special_params
if [[ ${1+_} ]]; then
# only declare `param` if $1 is set (even as null string)
local param="$1"
fi
# check if `param` is set (even as null string)
if [[ ${param+_} ]]; then
special_params=( --this-special-option "${param}" )
fi
cmd ${param+"${special_params[@]}"}
}
# cmd --this-special-option 'abc'
func 'abc'
# cmd --this-special-option ''
func ''
# cmd
func
```
Or more simple, if you only have to set an option:
```shell
func() {
if [[ ${1+_} ]]; then
# only declare `param` if $1 is set (even as null string)
local param="$1"
fi
cmd ${param+--this-special-option}
}
# cmd --this-special-option
func 'abc'
# cmd --this-special-option
func ''
# cmd
func
```

# Dracut Developer Guidelines
Please make sure to follow our [Contribution Guidelines](../CONTRIBUTING.md).
## git
Currently dracut lives on github.com.
* https://github.com/dracutdevs/dracut.git
Pull requests should be filed preferably on github nowadays.
### Code Format
It is recommended, that you install a plugin for your editor, which reads in `.editorconfig`.
Additionally `emacs` and `vim` config files are provided for convenience.
To reformat C files use `astyle`:
```console
$ astyle --options=.astylerc <FILE>
```
For convenience there is also a Makefile `indent-c` target `make indent-c`.
To reformat shell files use `shfmt`:
```console
$ shfmt_version=3.2.4
$ wget "https://github.com/mvdan/sh/releases/download/v${shfmt_version}/shfmt_v${shfmt_version}_linux_amd64" -O shfmt
$ chmod u+x shfmt
$ ./shfmt -w -s .
```
or
```console
$ GO111MODULE=on go get mvdan.cc/sh/v3/cmd/shfmt
$ $GOPATH/bin/shfmt -w -s .
```
or if `shfmt` is already in your `PATH`, use `make indent`.
Some IDEs already have support for shfmt.
For convenience the `make indent` Makefile target also calls shfmt, if it is in `$PATH`.
### Commit Messages
Commit messages should answer these questions:
* What?: a short summary of what you changed in the subject line.
* Why?: what the intended outcome of the change is (arguably the most important piece of information that should go into a message).
* How?: if multiple approaches for achieving your goal were available, you also want to explain why you chose the used implementation strategy.
Note that you should not explain how your change achieves your goal in your commit message.
That should be obvious from the code itself.
If you cannot achieve that clarity with the used programming language, use comments within the code instead.
The commit message is primarily the place for documenting the why.
Commit message titles should follow [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/).
Format is `<type>[optional scope]: <description>`, where `type` is one of:
* fix: A bug fix
* feat: A new feature
* perf: A code change that improves performance
* refactor: A code change that neither fixes a bug nor adds a feature
* style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
* test: Adding missing tests or correcting existing tests
* docs: Documentation only changes
* revert: Reverts a previous commit
* chore: Other changes that don't modify src or test files
* build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
* ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
`scope` should be the module name (without numbers) or:
* cli: for the dracut command line interface
* rt: for the dracut initramfs runtime logic
* functions: for general purpose dracut functions
Commit messages are checked with [Commisery](https://github.com/tomtom-international/commisery).
## Writing modules
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 later on.
* 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.
Most of the functionality that dracut implements are actually implemented
by dracut modules. dracut modules live in modules.d, and have the following
structure:
```
dracut_install_dir/modules.d/
00modname/
module-setup.sh
check
<other files as needed by the hook>
```
`00modname`: The name of the module prefixed by a two-digit numeric sort code.
The numeric code must be present and in the range of 00 - 99.
Modules with lower numbers are installed first. This is important
because the dracut install functions (which install files onto
the initrd) refuse to overwrite already installed files. This makes
it easy for an earlier module to override the functionality of a
later module, so that you can have a distro or system specific
module override or modify the functionality of a generic module
without having to patch the more generic module.
`module-setup.sh`:
dracut sources this script to install the functionality that a
module implements onto the initrd. For the most part, this amounts
to copying files from the host system onto the initrd in a controlled
manner.
`install()`:
This function of module-setup.sh is called to install all
non-kernel files. dracut supplies several install functions that are
specialized for different file types. Browse through dracut-functions
for more details. dracut also provides a $moddir variable if you
need to install a file from the module directory, such as an initrd
hook, a udev rule, or a specialized executable.
`installkernel()`:
This function of module-setup.sh is called to install all
kernel related files.
`check()`:
dracut calls this function to check and see if a module can be installed
on the initrd.
When called without options, check should check to make sure that
any files it needs to install into the initrd from the host system
are present. It should exit with a 0 if they are, and a 1 if they are
not.
When called with $hostonly set, it should perform the same check
that it would without it set, and it should also check to see if the
functionality the module implements is being used on the host system.
For example, if this module handles installing support for LUKS
encrypted volumes, it should return 0 if all the tools to handle
encrpted volumes are available and the host system has the root
partition on an encrypted volume, 1 otherwise.
`depends()`:
This function should output a list of dracut modules
that it relies upon. An example would be the nfs and iscsi modules,
which rely on the network module to detect and configure network
interfaces.
Any other files in the module will not be touched by dracut directly.
You are encouraged to provide a README that describes what the module is for.
### Hooks
init has the following hook points to inject scripts:
`/lib/dracut/hooks/cmdline/*.sh`
scripts for command line parsing
`/lib/dracut/hooks/pre-udev/*.sh`
scripts to run before udev is started
`/lib/dracut/hooks/pre-trigger/*.sh`
scripts to run before the main udev trigger is pulled
`/lib/dracut/hooks/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 /lib/dracut/hooks/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".
`/lib/dracut/hooks/pre-mount/*.sh`
scripts to run before the root filesystem is mounted
Network filesystems like NFS that do not use device files are an
exception. Root can be mounted already at this point.
`/lib/dracut/hooks/mount/*.sh`
scripts to mount the root filesystem
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.
`/lib/dracut/hooks/pre-pivot/*.sh`
scripts to run before latter initramfs cleanups
`/lib/dracut/hooks/cleanup/*.sh`
scripts to run before the real init is executed and the initramfs
disappears
All processes started before should be killed here.
## Testsuite
### Rootless in a container with podman
```console
$ cd <DRACUT_SOURCE>
$ podman pull [CONTAINER]
$ podman run --rm -it \
--cap-add=SYS_PTRACE --user 0 \
-v /dev:/dev -v ./:/dracut:z \
[CONTAINER] \
bash -l
# cd /dracut
# ./configure
# make -j $(getconf _NPROCESSORS_ONLN)
# cd test
# make V=1 SKIP="16 60 61" clean check
```
with `[CONTAINER]` being one of the
[github `dracutdevs` containers](https://github.com/orgs/dracutdevs/packages),
e.g. `ghcr.io/dracutdevs/fedora:latest`.
### On bare metal
For the testsuite to pass, you will have to install at least the software packages
mentioned in the `test/container` Dockerfiles.
```
$ sudo make clean check
```
in verbose mode:
```
$ sudo make V=1 clean check
```
only specific test:
```
$ sudo make TESTS="01 20 40" clean check
```
only runs the 01, 20 and 40 tests.
debug a specific test case:
```
$ cd TEST-01-BASIC
$ sudo make clean setup run
```
... change some kernel parameters in `test.sh` ...
```
$ sudo make run
```
to run the test without doing the setup.

Dracut supports running against a sysroot directory that is different
from the actual root (/) directory of the running system. It is most
useful for creating/bootstrapping a new system that may or may not be
using the same CPU architecture as the host system, i.e. building a
whole Linux system with a cross-compiler framework like Yocto.
The user-visible frontend change is the introduction of a new option
called "-r" or "--sysroot". It expects a directory that contains the
complete Linux system that has all the files (kernel drivers, firmware,
executables, libraries and others) necessary to construct the initramfs.
E.g: dracut --sysroot /path/to/sysroot initramfs.img kernelversion
To support this, a new global variable was introduced inside dracut.
This variable is called "dracutsysrootdir" and all the files installed
into the initramfs image is searched relative to the sysroot directory.
This variable can also be set externally to dracut without using option
-r/--sysroot.
There are other details that are necessary to tweak to be able to
run on cross-compiled (a.k.a. foreign) binaries.
dracut uses these crucial utilities during its operation:
ldd
===
It lists dynamic library dependencies for executables or libraries
ldconfig
========
It creates /etc/ld.so.cache, i.e. the cached information about libraries
known to the system.
These utilities the way they exist on the host system only work on
the host system.
To support cross-compiled binaries, a different ldd variant is needed that
works on those binaries. One such ldd script is found at
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
ldconfig in GLIBC as is does support a sysroot with its -r option.
Extra environment variables needed to run dracut on the sysroot are
documented in the dracut(8) man page.
For the Plymouth boot splash to be added to the initramfs image,
this gitlab PR is needed for Plymouth:

You may be able to use standard systemd *fstab*(5) syntax to

you will have to exclude the "systemd" dracut module and any modules

(prefix with "LABEL="). You don't have to specify full UUID. Just its beginning
will suffice, even if its ambiguous. All matching devices will be probed.
This parameter is recommended, but not required. If not present, all block
devices will be probed, which may significantly increase boot time.

[NOTE]
===============================
Your LUKS partition must match your key file.
dracut pipes key to cryptsetup with _-d -_ argument, therefore you need to pipe
to crypsetup luksFormat with _-d -_, too!
dracut provides keys to cryptsetup with _-d_ (an older alias for
_--key-file_). This uses the entire binary
content of the key file as part of the secret. If
you pipe a password into cryptsetup *without* _-d_ or _--key-file_,
it will be treated as text user input, and only characters before
the first newline will be used. Therefore, when you're creating
an encrypted partition for dracut to mount, and you pipe a key into
_cryptsetup luksFormat_,you must use _-d -_.
Here is an example for a key encrypted with GPG (warning:
_--batch-mode_ will overwrite the device without asking for
confirmation):
Here follows example for key encrypted with GPG:
[listing]
--
gpg --quiet --decrypt rootkey.gpg | \
cryptsetup --batch-mode --key-file - \
luksFormat /dev/sda47
cryptsetup -d - -v --cipher serpent-cbc-essiv:sha256 \
--key-size 256 luksFormat /dev/sda3
--
If you use unencrypted key files, just use the key file pathname
instead of the standard input. For a random key with 256 bits of
entropy, you might use:
If you use plain keys, just add path to _-d_ option:
[listing]
--
head -32c /dev/urandom > rootkey.key
cryptsetup --batch-mode --key-file rootkey.key \
luksFormat /dev/sda47
cryptsetup -d rootkey.key -v --cipher serpent-cbc-essiv:sha256 \
--key-size 256 luksFormat /dev/sda3
--
You can also use regular key files on an encrypted _keydev_.
Compared to using GPG encrypted keyfiles on an unencrypted
device this provides the following advantages:
- you can unlock your disk(s) using multiple passphrases
- better security by not loosing the key stretching mechanism
To use an encrypted _keydev_ you *must* ensure that it becomes
available by using the keyword `keysource`, e.g.
`rd.luks.uuid=keysource:aaaa`
_aaaa_ being the uuid of the encrypted _keydev_.
Example:
Lets assume you have three disks _A_, _B_ and _C_ with the uuids
_aaaa_, _bbbb_ and _cccc_. +
You want to unlock _A_ and _B_ using keyfile _keyfile_. +
The unlocked volumes be _A'_, _B'_ and _C'_ with the uuids
_AAAA_, _BBBB_ and _CCCC_. +
_keyfile_ is saved on _C'_ as _/keyfile_.
One luks keyslot of each _A_, _B_ and _C_ is setup with a
passphrase. +
Another luks keyslot of each _A_ and _B_ is setup with _keyfile_.
To boot this configuration you could use:
[listing]
--
rd.luks.uuid=aaaa
rd.luks.uuid=bbbb
rd.luks.uuid=keysource:cccc
rd.luks.key=/keyfile:UUID=CCCC
--
Dracut asks for the passphrase for _C_ and uses the
keyfile to unlock _A_ and _B_. +
If getting the passphrase for _C_ fails it falls back to
asking for the passphrases for _A_ and _B_.
If you want _C'_ to stay unlocked, specify a luks name for
it, e.g. `rd.luks.name=cccc=mykeys`, otherwise it gets closed
when not needed anymore.

%description
dracut contains tools to create bootable initramfses for the Linux
kernel. Unlike previous implementations, dracut hard-codes as little
as possible into the initramfs. dracut contains various modules which
are driven by the event-based udev. Having root on MD, DM, LVM2, LUKS
is supported as well as NFS, iSCSI, NBD, FCoE with the dracut-network
package.

MKINITRD(8)
===========
:doctype: manpage
:man source: dracut
:man manual: dracut
NAME
----
mkinitrd-suse - is a compat wrapper, which calls dracut to generate an initramfs
SYNOPSIS
--------
*mkinitrd* ['OPTION...']
DESCRIPTION
-----------
*mkinitrd* creates an initramfs image <initrd-image> for the kernel with
version <kernel-version> by calling *dracut*.
[IMPORTANT]
This version of mkinitrd is provided for compatibility with older
versions of mkinitrd. If a more fine grained control over the
resulting image is needed, *dracut* should be called directly.
OPTIONS
-------
**-R, --version**::
print info about the version
**-k** _<kernel_list>_::
List of kernel images for which initrd files are created (relative
to _boot_dir_), Image name should begin with the following string,
defaults to _vmlinux_ on ppc/ppc64, _image_ on s390/s390x and _vmlinuz_
for everything else.
**-i** _<initrd_list>_::
List of file names (relative to _boot_dir_) for the initrd; positions
have to match the _kernel_list_. Defaults to _initrd_.
**-m** _<module_list>_::
Modules to include in initrd, defaults to _INITRD_MODULES_ variable
in */etc/sysconfig/kernel*.
**-f** _<feature_list>_::
Features to be enabled for the initrd. In general mkinitrd
configures the initrd for the root device it is started from. With
this option additional feature can be enabled.
**-b** _<bootdir>_::
Boot directory, defaults to */boot*, where the initrd is created.
**-d** _<root_device>_::
Root device, defaults to the device from which the root_dir is
mounted; overwrites the rootdev environment variable if set
**-s** _<size>_::
Add splash animation and bootscreen to initrd.
**-D** _<interface>::
Run dhcp on the specified interface (for example "eth0").
**-I** _<interface>::
Configure the specified interface statically.
**-a** _<acpi_dsdt>::
Attach compiled ACPI DSDT (Differentiated System Description Table)
to initrd. This replaces the DSDT of the BIOS. Defaults to the
_ACPI_DSDT_ variable in */etc/sysconfig/kernel*.
**-M** _<map>::
System.map file to use.
**-B**::
Dont run the *update-bootloader(8)* script after the initrd(s) have
been created. This is useful if you call mkinitrd(8) for anything
else than the running system.
**-A**::
Create a so called "monster initrd" which includes all available
features and modules. This calls dracut with --no-hostonly and
--no-hostonly-cmdline parameters internally, instead of the default
--hostonly and --hostonly-cmdline.
**-v, --verbose**::
increase verbosity level
**-L**::
Disable logging to _/var/log/YaST2/mkinitrd.log_. This is useful for
testing if you dont want to clutter the system log.
**--help**::
print a help message and exit.
AVAILABILITY
------------
The mkinitrd command is part of the dracut package and is available from
link:$$https://dracut.wiki.kernel.org$$[https://dracut.wiki.kernel.org]

MKINITRD(8)
=========
:doctype: manpage
:man source: dracut
:man manual: dracut
NAME
----
mkinitrd - is a compat wrapper, which calls dracut to generate an initramfs
SYNOPSIS
--------
*mkinitrd* ['OPTION...'] [<initrd-image>] <kernel-version>
DESCRIPTION
-----------
mkinitrd creates an initramfs image <initrd-image> for the kernel with
version <kernel-version> by calling "dracut".
[IMPORTANT]
If a more fine grained control over the resulting image is needed,
"dracut" should be called directly.
OPTIONS
-------
**--version**::
print info about the version
**-v, --verbose**::
increase verbosity level
**-f, --force**::
overwrite existing initramfs file.
**--image-version*::
append the kernel version to the target image
<initrd-image>-<kernel-version>.
**--with=<module>**::
add the kernel module <module> to the initramfs.
**--preload=<module>**::
preload the kernel module <module> in the initramfs before any other kernel
modules are loaded. This can be used to ensure a certain device naming,
which should in theory be avoided and the use of symbolic links in /dev is
encouraged.
**--nocompress**::
do not compress the resulting image.
**--help**::
print a help message and exit.
AVAILABILITY
------------
The mkinitrd command is part of the dracut package and is available from
link:$$https://dracut.wiki.kernel.org$$[https://dracut.wiki.kernel.org]
