Another option might be using UFSIDs, but of course that only
applies for UFS filesystems (or partitions holding them):

	Any partitions with ufsid labels can be mounted in this way,
	eliminating the need to manually create permanent labels,
	while still enjoying the benefits of device name independent
	mounting.
