Subject:    Patch: mount: Allow mounting single devices by UUID

mount -a
can mount devices from /etc/fstab using UUID=... designation (if that's 
configured)

mount /dev/sda
will fail to mount /dev/sda if it is only listed by UUID in the fstab 
file. The patch lets mount check and parse UUID entries in fstab, and 
also find a match based on UUID. The behavior is now the same as for 
util-linux-ng-mount.

Patch is based on 1.18.5 (but should apply on later versions as well).

I've tested and used this patch in the OpenPLi distribution.

Kind regards,
Mike Looijmans
