This hook provides a mechanism to inject arbitrary scripts into each hook stage
of the initramfs. In mkinitcpio.conf, define any of the following variables to
the path of a script (compiled binaries are not guaranteed to work) that will
copied into the initramfs and executed in the corresponding hook stage:

- rclocal_earlyhook
- rclocal_hook
- rclocal_latehook
- rclocal_cleanup

Any undefined variable will be ignored, but a variable that specifies the path
to a non-existent file will trigger an error. Each script will have mode 0755
set when copied into the initramfs.
