 125                          directory instead of the system-wide installed in

 140                         If SOURCE is a file, it will be installed to TARGET
 141                          in the final initramfs.

 147   --bzip2               Compress the generated initramfs using bzip2.
 148                          Make sure your kernel has bzip2 decompression support
 149                          compiled in, otherwise you will not be able to boot.
 150   --lzma                Compress the generated initramfs using lzma.
 151                          Make sure your kernel has lzma support compiled in,
 152                          otherwise you will not be able to boot.
 153   --xz                  Compress the generated initramfs using xz.
 154                          Make sure that your kernel has xz support compiled
 155                          in, otherwise you will not be able to boot.
 156   --compress [COMPRESSION] Compress the generated initramfs with the
 157                          passed compression program.  Make sure your kernel
 158                          knows how to decompress the generated initramfs,
 159                          otherwise you will not be able to boot.
 160   --no-compress         Do not compress the generated initramfs.  This will
 161                          override any other compression options.
 162   --list-modules        List all available dracut modules.
 163   -M, --show-modules    Print included module's name to standard output during
 164                          build.
 165   --keep                Keep the temporary initramfs for debugging purposes
 166   --printsize           Print out the module install size
 167   --sshkey [SSHKEY]     Add ssh key to initramfs (use with ssh-client module)
 168
 169 If [LIST] has multiple arguments, then you have to put these in quotes.
