This is the fstab of my notebook:

# Device		Mountpoint	FStype	Options		Dump	Pass#
/dev/label/2swap	none		swap	sw		0	0
/dev/ufs/2root		/		ufs	rw		1	1
/dev/ufs/2tmp		/tmp		ufs	rw,async	2	2
/dev/ufs/2usr		/usr		ufs	rw		2	2
/dev/ufs/2var		/var		ufs	rw		2	2

I can take out the HD and boot from it via USB-adaptor or put it into another 
machine. It all doesn't matter, I don't care about device IDs at all. The geom 
label class has made life much easier.

You only have to label the partitions with "tunefs -L" and the swap partition 
with "glabel label".
