 173                          Make sure that your kernel has lz4 support compiled

 175   --compress [COMPRESSION] Compress the generated initramfs with the
 176                          passed compression program.  Make sure your kernel
 177                          knows how to decompress the generated initramfs,
 178                          otherwise you will not be able to boot.
 179   --no-compress         Do not compress the generated initramfs.  This will
 180                          override any other compression options.
 181   --list-modules        List all available dracut modules.
 182   -M, --show-modules    Print included module's name to standard output during
 183                          build.
