                        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.

  --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

  --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.
