Can you do the same with gpt or ufs labels? Glabel is dangerous since once
you label a partition, you can only reference it through the label safely.
Glabel creates a new device/partition that's a little smaller than the
original. The old contents can be corrupted and weird things happen when
you newfs on the original device. Swap with glabel can confuse crash dumps.
And a few other weird edge cases (so it mostly works, but unpredictablely
fails). I'd suggest this tool at least warn that there be dragons around
glabel that aren't there for diskid, gpt or ufs label or any other fs based
label.

I'll have to give it a spin.
