This hook shrinks your initramdisk to a smaller size
by autodetecting your needed modules. Be sure to verify
included modules are correct and none are missing.
This hook must be run before other subsystem hooks in
order to take advantage of auto-detection. Any hooks
placed before 'autodetect' will be installed in full.
