It's worth mentioning that the /etc/fstab mechanisms for
mounting can work with ANY of the "identification names"
for meddia at the same time, this means you can mount one
drive (or even partition) as /dev/ad0s1d, the next one
as /dev/label/home, the next one as /dev/ufsid/1234567890
and so on. One doesn't replace the other.

The really handy thing about labels is that the drive's
position during the recognition by the system (ad0, ad1,
ad2, ...) doesn't matter. Say you move the hard drive
from a defective controller (ad0) to a PCI replacement
controller (ad4), labels won't change, and booting would
happen as usual.
