145 --gzip Compress the generated initramfs using gzip.
146 This will be done by default, unless another
147 compression option or --no-compress is passed.

152 Make sure your kernel has lzma support compiled in,
153 otherwise you will not be able to boot.
154 --xz Compress the generated initramfs using xz.
155 Make sure that your kernel has xz support compiled
156 in, otherwise you will not be able to boot.
157 --compress [COMPRESSION] Compress the generated initramfs with the
158 passed compression program. Make sure your kernel
159 knows how to decompress the generated initramfs,
160 otherwise you will not be able to boot.
161 --no-compress Do not compress the generated initramfs. This will
162 override any other compression options.
163 --list-modules List all available dracut modules.
164 -M, --show-modules Print included module's name to standard output during
166 --keep Keep the temporary initramfs for debugging purposes
