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.

27	default "0"
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.
45
46	  If you are not sure, leave it set to "0".
