| 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. | |

| 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". | |

| This setting is only meaningful if the INITRAMFS_SOURCE is | |
| contains a directory. Setting this group ID (GID) to something | |
