- config INITRAMFS_SOURCE
- string "Initramfs source file(s)"
- default ""
- help
- This can be either a single cpio archive with a .cpio suffix or a
- space-separated list of directories and files for building the
- initramfs image. A cpio archive should contain a filesystem archive
- to be used as an initramfs image. Directories should contain a
- filesystem layout to be included in the initramfs image. Files
- should contain entries according to the format described by the
- "usr/gen_init_cpio" program in the kernel tree.
- When multiple directories and files are specified then the
- initramfs image will be the aggregate of all of them.
- See <file:Documentation/early-userspace/README> for more details.
- If you are not sure, leave it blank.

- depends on INITRAMFS_SOURCE!=""
- default "0"
- help
- This setting is only meaningful if the INITRAMFS_SOURCE is
- contains a directory. Setting this user ID (UID) to something
- other than "0" will cause all files owned by that UID to be
- owned by user root in the initial ramdisk image.
- If you are not sure, leave it set to "0".
- config INITRAMFS_ROOT_GID
- int "Group ID to map to 0 (group root)"
- depends on INITRAMFS_SOURCE!=""
- default "0"
- help
- This setting is only meaningful if the INITRAMFS_SOURCE is
- contains a directory. Setting this group ID (GID) to something
- other than "0" will cause all files owned by that GID to be
