Subject: [PATCH] Create a symlink for the live image's base loop device

It is useful to know that loop device that the live image's / is mounted
from. Make a /run/initramfs/live-baseloop symlink that points to it.

Edited-By: harald@redhat.com: changed /dev/live-baseloop
                              to /run/initramfs/live-baseloop
