Usage: $dracut_cmd [OPTION]... [<initramfs> [<kernel-version>]]
Version: $DRACUT_VERSION
Creates initial ramdisk images for preloading modules
--kver [VERSION] Set kernel version to [VERSION].
-f, --force Overwrite existing initramfs file.
-a, --add [LIST] Add a space-separated list of dracut modules.
--force-add [LIST] Force to add a space-separated list of dracut modules
to the default set of modules, when -H is specified.
-o, --omit [LIST] Omit a space-separated list of dracut modules.
-m, --modules [LIST] Specify a space-separated list of dracut modules to
call when building the initramfs. Modules are located
in /usr/lib/dracut/modules.d.
This option forces dracut to only include the specified
dracut modules.
In most cases the --add option is what you want to use.
--add-drivers [LIST] Specify a space-separated list of kernel
modules to add to the initramfs.
--force-drivers [LIST]
Specify a space-separated list of kernel
modules to add to the initramfs and make sure they
are tried to be loaded via modprobe same as passing
rd.driver.pre=DRIVER kernel parameter.
--omit-drivers [LIST] Specify a space-separated list of kernel
modules not to add to the initramfs.
-d, --drivers [LIST] Specify a space-separated list of kernel modules to
exclusively include in the initramfs.
--filesystems [LIST] Specify a space-separated list of kernel filesystem
modules to exclusively include in the generic
initramfs.
-k, --kmoddir [DIR] Specify the directory where to look for kernel
modules.
--fwdir [DIR] Specify additional colon-separated list of directories
where to look for firmware files.
--libdirs [LIST] Specify a space-separated list of directories
where to look for libraries.
--kernel-only Only install kernel drivers and firmware files.
--no-kernel Do not install kernel drivers and firmware files.
--split-kernel Generate two initramfs files, one without kernel modules
and other with kernel modules only. The second one will
not be compressed if kernel modules are compressed.
--print-cmdline Print the kernel command line for the given disk layout.
--early-microcode Combine early microcode with ramdisk.
--no-early-microcode Do not combine early microcode with ramdisk.
--kernel-cmdline [PARAMETERS]
Specify default kernel command line parameters.
--strip Strip binaries in the initramfs.
--aggressive-strip Strip more than just debug symbol and sections,
for a smaller initramfs build. The --strip option must
also be specified.
--nostrip Do not strip binaries in the initramfs.
--hardlink Hardlink files in the initramfs.
--nohardlink Do not hardlink files in the initramfs.
--prefix [DIR] Prefix initramfs files with [DIR].
--noprefix Do not prefix initramfs files.
--mdadmconf Include local /etc/mdadm.conf file.
--nomdadmconf Do not include local /etc/mdadm.conf file.
--lvmconf Include local /etc/lvm/lvm.conf file.
--nolvmconf Do not include local /etc/lvm/lvm.conf file.
--fscks [LIST] Add a space-separated list of fsck helpers.
--nofscks Inhibit installation of any fsck helpers.
--ro-mnt Mount / and /usr read-only by default.
-h, --help This message.
--debug Output debug information of the build process.
--profile Output profile information of the build process.
-L, --stdlog [0-6] Specify logging level (to standard error)
0 - suppress any messages
1 - only fatal errors
2 - all errors
3 - warnings
4 - info
5 - debug info (here starts lots of output)
6 - trace info (and even more)
-v, --verbose Increase verbosity level.
-q, --quiet Decrease verbosity level.
-c, --conf [FILE] Specify configuration file to use.
Default: /etc/dracut.conf
--confdir [DIR] Specify configuration directory to use *.conf files
from. Default: /etc/dracut.conf.d
--tmpdir [DIR] Temporary directory to be used instead of default
${TMPDIR:-/var/tmp}.
-H, --hostonly Host-only mode: Install only what is needed for
booting the local host instead of a generic host.
-N, --no-hostonly Disables host-only mode.
--hostonly-mode [MODE]
Specify the host-only mode to use. [MODE] could be
one of "sloppy" or "strict". "sloppy" mode is used
by default.
In "sloppy" host-only mode, extra drivers and modules
will be installed, so minor hardware change won't make
the image unbootable (e.g. changed keyboard), and the
image is still portable among similar hosts.
With "strict" mode enabled, anything not necessary
for booting the local host in its current state will
not be included, and modules may do some extra job
to save more space. Minor change of hardware or
environment could make the image unbootable.
DO NOT use "strict" mode unless you know what you
are doing.
--hostonly-cmdline Store kernel command line arguments needed
in the initramfs.
--no-hostonly-cmdline Do not store kernel command line arguments needed
in the initramfs.
--no-hostonly-default-device
Do not generate implicit host devices like root,
swap, fstab, etc. Use "--mount" or "--add-device"
to explicitly add devices as needed.
--hostonly-i18n Install only needed keyboard and font files according
to the host configuration (default).
--no-hostonly-i18n Install all keyboard and font files available.
--hostonly-nics [LIST]
Only enable listed NICs in the initramfs. The list can
be empty, so other modules can install only the
necessary network drivers.
--persistent-policy [POLICY]
Use [POLICY] to address disks and partitions.
POLICY can be any directory name found in /dev/disk
(e.g. "by-uuid", "by-label"), or "mapper" to use
/dev/mapper device names (default).
--fstab Use /etc/fstab to determine the root device.
--add-fstab [FILE] Add file to the initramfs fstab.
--mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
Mount device [DEV] on mountpoint [MP] with filesystem
[FSTYPE] and options [FSOPTS] in the initramfs.
--mount "[MP]" Same as above, but [DEV], [FSTYPE] and [FSOPTS] are
determined by looking at the current mounts.
--add-device "[DEV]" Bring up [DEV] in initramfs.
-i, --include [SOURCE] [TARGET]
Include the files in the SOURCE directory into the
Target directory in the final initramfs.
If SOURCE is a file, it will be installed to TARGET
in the final initramfs.
-I, --install [LIST] Install the space separated list of files into the
initramfs.
--install-optional [LIST]
Install the space separated list of files into the
initramfs, if they exist.
--gzip Compress the generated initramfs using gzip.
This will be done by default, unless another
compression option or --no-compress is passed.
--bzip2 Compress the generated initramfs using bzip2.
Make sure your kernel has bzip2 decompression support
compiled in, otherwise you will not be able to boot.
--lzma Compress the generated initramfs using lzma.
Make sure your kernel has lzma support compiled in,
otherwise you will not be able to boot.
--xz Compress the generated initramfs using xz.
Make sure that your kernel has xz support compiled
in, otherwise you will not be able to boot.
--lzo Compress the generated initramfs using lzop.
Make sure that your kernel has lzo support compiled
in, otherwise you will not be able to boot.
--lz4 Compress the generated initramfs using lz4.
Make sure that your kernel has lz4 support compiled
in, otherwise you will not be able to boot.
--zstd Compress the generated initramfs using Zstandard.
Make sure that your kernel has zstd support compiled
in, otherwise you will not be able to boot.
--compress [COMPRESSION]
Compress the generated initramfs with the
passed compression program. Make sure your kernel
knows how to decompress the generated initramfs,
otherwise you will not be able to boot.
--no-compress Do not compress the generated initramfs. This will
override any other compression options.
--squash-compressor [COMPRESSION]
Specify the compressor and compressor specific options
used by mksquashfs if squash module is called when
building the initramfs.
--list-modules List all available dracut modules.
-M, --show-modules Print included module's name to standard output during
build.
--keep Keep the temporary initramfs for debugging purposes.
--printsize Print out the module install size.
--sshkey [SSHKEY] Add SSH key to initramfs (use with ssh-client module)
--logfile [FILE] Logfile to use (overrides configuration setting)
--check-supported Check to ensure that modules are marked supported when
using a kernel that is configured to check the
support status of a module before loading.
--reproducible Create reproducible images.
--no-reproducible Do not create reproducible images.
--loginstall [DIR] Log all files installed from the host to [DIR].
--regenerate-all Regenerate all initramfs images at the default location
for the kernel versions found on the system.
-p, --parallel Use parallel processing if possible (currently only
supported --regenerate-all)
images simultaneously.
--no-create-sysusers Create system users on every boot, instead of creating
them only when the initramfs is generated.
--version Display version.
If [LIST] has multiple arguments, then you have to put these in quotes.
For example:
# dracut --add-drivers "module1 module2" ...
EOF

_long_version() {
[[ $dracutbasedir ]] || dracutbasedir=/usr/lib/dracut
