# Configuration for initramfs
#
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.
config INITRAMFS_ROOT_UID
int "User ID to map to 0 (user root)"
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
owned by group root in the initial ramdisk image.
If you are not sure, leave it set to "0".
