That will work, but is not as nice as GPT labels. >> You did not say whether this was a GPT disk, > > Is there a way to check this? The first line of 'gpart show' output for a disk identifies the partitioning scheme: % gpart show ada0 => 34 500118125 ada0 GPT (238G) ... GPT labels can be set with 'gpart modify -l mynewlabel ...'. On MBR, I use UFS labels where possible, and glabel only where the partition has no built-in metadata, like swap.
