Nice.

Yeah, this stuff does not really fit in to the path notation stuff,
unless we use the udev-style link names, which some people like to
avoid, and prefer some more abstract thing here.

We have UUID=, LABEL= for mount and fstab, I think PARTUUID=,
PARTLABEL= matches this.

We can always change that, if something better comes up before this
gets official. :)
