+# Generate a cpio packed initramfs. It uses gen_init_cpio to generate
+# the cpio archive, and then compresses it.

+Usage:
+$0 [-o <file>] [-u <uid>] [-g <gid>] {-d | <cpio_source>} ...
+	-o <file>      Create compressed initramfs file named <file> using
+		       gen_init_cpio and compressor depending on the extension
+	-u <uid>       User ID to map to user ID 0 (root).
+		       <uid> is only meaningful if <cpio_source> is a
+		       directory.  "squash" forces all files to uid 0.
+	-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
+to reset the root/group mapping.
