glabel looks to place a label on the whole disk, but the manpage is unclear (to me) how the partitions are handled. If I use glabel to label a disk "test" and this disk has 4 partitions on it, then how is each partition accessed? testp1...testp4 for gpt? The other option seems to be to use tunefs or a partitioning tool to label each partition, which is even more ugly imo.
