ufs labels are handled by glabel.

But <disk1>p# contains the same filesystem with the same label as
mirror/gm0p#. If glabel sees <disk1>p# on boot before mirror/gm0p# it
may associate ufs/<name> with <disk1>p# instead of mirror/gm0p#.

This can happen with "glabel label"-labels, ufs-labels and gpt-labels.


If you want verbose names, you might be able to use gconcat (with one
component) since gconcat can use hardcoded provider names, which
should avoid this problem.

It would be nice to add the possibility to hardcode providers to
glabel.
