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".
