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

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

[Brian C. Lane]

From: "Brian C. Lane" <bcl-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

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

changed the symlink to /run/initramfs/live-baseloop, because /dev should be only
be maintained by udev and the kernel
