  8	help
  9	  This can be either a single cpio archive with a .cpio suffix or a
 10	  space-separated list of directories and files for building the
 11	  initramfs image.  A cpio archive should contain a filesystem archive
 12	  to be used as an initramfs image.  Directories should contain a
 13	  filesystem layout to be included in the initramfs image.  Files
 14	  should contain entries according to the format described by the
 15	  "usr/gen_init_cpio" program in the kernel tree.
 16
 17	  When multiple directories and files are specified then the
 18	  initramfs image will be the aggregate of all of them.
 19
 20	  See <file:Documentation/early-userspace/README> for more details.

 22	  If you are not sure, leave it blank.

 28	help
 29	  This setting is only meaningful if the INITRAMFS_SOURCE is
 30	  contains a directory.  Setting this user ID (UID) to something
 31	  other than "0" will cause all files owned by that UID to be
 32	  owned by user root in the initial ramdisk image.
 33
 34	  If you are not sure, leave it set to "0".

 36config INITRAMFS_ROOT_GID
 37	int "Group ID to map to 0 (group root)"
 38	depends on INITRAMFS_SOURCE!=""
 39	default "0"
 40	help
 41	  This setting is only meaningful if the INITRAMFS_SOURCE is
 42	  contains a directory.  Setting this group ID (GID) to something
 43	  other than "0" will cause all files owned by that GID to be
 44	  owned by group root in the initial ramdisk image.
