Howto configure the Linux kernel / usr


 * Configuration for initramfs
 * Configuration for initramfs

"Initramfs source file(s)"
 * Option: INITRAMFS_SOURCE
 * Kernel Versions: 2.6.15.6 ...
 * default ""
 * 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.

"User ID to map to 0 (user root)"
 * Option: INITRAMFS_ROOT_UID
 * Kernel Versions: 2.6.15.6 ...
 * depends on INITRAMFS_SOURCE!=""
 * default "0"
 * 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".

"Group ID to map to 0 (group root)"
 * Option: INITRAMFS_ROOT_GID
 * Kernel Versions: 2.6.15.6 ...
 * depends on INITRAMFS_SOURCE!=""
 * default "0"
 * 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".
