Since cp won't copy a directory over a symlink, any updates that were
supposed to go into e.g. /lib would get dropped if you had /updates/lib
as an actual directory, but the target system had /lib->/usr/lib.
If we're about to start a Live image (i.e. if /dev/mapper/live-rw
exists) this script will take any files found in /updates (inside the
initramfs!) and and copy them into $NEWROOT.
This allows for hotfixes to be applied to existing Live images without
rebuilding the entire image.
