    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. :)
