glabeled units as consumers? gstriping swap and /tmp? (was Re: graid5 or gvinums - bootable?)

Not quite sure what you're asking. Labeling the disks, then using the
labels in the mirror or raid, or applying a label to the resultant
mirror or raid?

In the former case, I don't think that's necessary, given that the geom
taste functions will find the correct consumers regardless.

As for the latter, the geom providers are set up with unique, canonical
device names, so glabel may be unnecessary.

Since my disks are not hot-swappable, the machines will need to reboot
to notice replacements anyways. A single swap slice in the same spot on
each disk works fine for me.

In theory. I've never bothered, because I don't use /tmp for anything
more than what the OS itself uses. It's not worth the added complexity
for my applications.
