                         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 hostonly mode to use. <mode> could be
                        one of "sloppy" or "strict". "sloppy" mode is used
                        by default.
                        In "sloppy" hostonly mode, extra drivers and modules
                        will be installed, so minor hardware change won't make
                        the image unbootable (eg. 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.
  --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"
  --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
  --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.
  --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.
  --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)

If [LIST] has multiple arguments, then you have to put these in quotes.
