- -u <uid> User ID to map to user ID 0 (root).
- <uid> is only meaningful if <cpio_source> is a

- -g <gid> Group ID to map to group ID 0 (root).
- <gid> is only meaningful if <cpio_source> is a
- directory. "squash" forces all files to gid 0.
- <cpio_source> File list or directory for cpio archive.
- If <cpio_source> is a .cpio file it will be used
- as direct input to initramfs.
- -d Output the default cpio list.
-
-All options except -o and -l may be repeated and are interpreted
-sequentially and immediately. -u and -g states are preserved across
-<cpio_source> options so an explicit "-u 0 -g 0" is required
