Commit 9ba4bcb645
("initramfs: read CONFIG_RD_ variables for initramfs
compression") removed the users of the various INITRAMFS_COMPRESSION_*
Kconfig symbols. So since v3.13 the entire "Built-in initramfs
compression mode" choice is a set of knobs connected to nothing. The
entire choice can safely be removed.

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".
