23 <uid> is only meaningful if <cpio_source> is a
24 directory. "squash" forces all files to uid 0.
25 -g <gid> Group ID to map to group ID 0 (root).
26 <gid> is only meaningful if <cpio_source> is a
27 directory. "squash" forces all files to gid 0.
28 <cpio_source> File list or directory for cpio archive.
29 If <cpio_source> is a .cpio file it will be used
30 as direct input to initramfs.
