 145                         If SOURCE is a file, it will be installed to TARGET

 154                          compiled in, otherwise you will not be able to boot.
 155   --lzma                Compress the generated initramfs using lzma.
 156                          Make sure your kernel has lzma support compiled in,
 157                          otherwise you will not be able to boot.
 158   --xz                  Compress the generated initramfs using xz.
 159                          Make sure that your kernel has xz support compiled
 160                          in, otherwise you will not be able to boot.
 161   --compress [COMPRESSION] Compress the generated initramfs with the
 162                          passed compression program.  Make sure your kernel
 163                          knows how to decompress the generated initramfs,
 164                          otherwise you will not be able to boot.
 165   --no-compress         Do not compress the generated initramfs.  This will
 166                          override any other compression options.
 167   --list-modules        List all available dracut modules.
 168   -M, --show-modules    Print included module's name to standard output during
 169                          build.
 170   --keep                Keep the temporary initramfs for debugging purposes
 171   --printsize           Print out the module install size
 172   --sshkey [SSHKEY]     Add ssh key to initramfs (use with ssh-client module)
 173
 174 If [LIST] has multiple arguments, then you have to put these in quotes.
