Usage: $dracut_cmd [OPTION]... [<initramfs> [<kernel-version>]]
Version: $DRACUT_VERSION
Creates initial ramdisk images for preloading modules
-h, --help Display all options
If a [LIST] has multiple arguments, then you have to put these in quotes.
For example:
# dracut --add-drivers "module1 module2" ...
EOF
}
long_usage() {
# 80x25 linebreak here ^
cat << EOF
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.
[OUTPUT_FILE] --rebuild
Append the current arguments to those with which the
input initramfs image was built. This option helps in
incrementally building the initramfs for testing.

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

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.

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.

--no-kernel Do not install kernel drivers and firmware files.
--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. Despite
its name, this command only sets initrd 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.

--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
--add-confdir [DIR] Add an extra configuration directory to use *.conf
files from. If the directory is not existed, will
look for subdirectory under confdir.
--tmpdir [DIR] Temporary directory to be used instead of default
${TMPDIR:-/var/tmp}.
-r, --sysroot [DIR] Specify sysroot directory to collect files from.
-l, --local Local mode. Use modules from the current working
directory instead of the system-wide installed in
/usr/lib/dracut/modules.d.
Useful when running dracut from a git checkout.
-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.
--remove [LIST] Remove a space-separated list of files and directories
from the initramfs (supports globbing).
--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.
--compress-level [LEVEL]
Compression level passed to compression program.
--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.
--enhanced-cpio Attempt to reflink cpio file data using 3cpio/dracut-cpio.
--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.
--printconfig Print the computed configuration and exit.
--sshkey [SSHKEY] Add SSH key to initramfs (use with ssh-client module).

--uefi-splash-image [FILE]
Use [FILE] as a splash image when creating an UEFI
executable. Requires bitmap (.bmp) image format.
--kernel-image [FILE] Location of the kernel image.
--sbat [PARAMETERS] The SBAT parameters to be added to .sbat.
The string "sbat,1,SBAT Version,sbat,1,
https://github.com/rhboot/shim/blob/main/SBAT.md" is
already added by default.
--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.
--version Display version.
If [LIST] has multiple arguments, then you have to put these in quotes.
