19 -o <file> Create compressed initramfs file named <file> using
21 -u <uid> User ID to map to user ID 0 (root).
22 <uid> is only meaningful if <cpio_source> is a

25 <gid> is only meaningful if <cpio_source> is a
28 If <cpio_source> is a .cpio file it will be used
30 -d Output the default cpio list.
32 All options except -o and -l may be repeated and are interpreted
33 sequentially and immediately. -u and -g states are preserved across
34 <cpio_source> options so an explicit "-u 0 -g 0" is required
