                         If optional [OUTPUT_FILE] is not provided, the input

                         This option forces dracut to only include the specified
                         dracut modules.

                         modules.

                         also be specified.

  -L, --stdlog [0-6]    Specify logging level (to standard error)
                         0 - suppress any messages
                         1 - only fatal errors
                         2 - all errors
                         3 - warnings

  --tmpdir [DIR]        Temporary directory to be used instead of default

  -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.
  --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.

  --xz                  Compress the generated initramfs using xz.
                         Make sure that your kernel has xz support compiled

  --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.

  --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.
