| 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. |

| 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)" |

| 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. |
