If we're going to make a change maybe we should allocate an extra
	bit for 32 partitions, though we will probably want to limit most
	devices to 22 partitions to avoid having to enlarge on-disk
	disklabels.

	Maybe even have reserve a minor number for the raw partition to
	be the device name without a letter)?
