The kernel has support for (nearly) every compression algorithm known to man, each to handle some particular microscopic niche. Unfortunately all of these always get compiled in if you want to support INITRDs, and can be only disabled when CONFIG_EXPERT is set. I don't see why I need to set EXPERT just to properly configure the initrd compression algorithms, and not always include every possible algorithm Usually the initrd is just compressed with gzip anyways, at least that's true on all distributions I use. Remove the dependencies for initrd compression on CONFIG_EXPERT. Make the various options just default y, which should be good enough to not break any previous configuration.

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.
