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.
