Your best bet is to use ufs or gpt labels.

# Device                Mountpoint      FStype  Options         Dump
Pass#

/dev/gpt/dune-swap      none            swap    sw              0       0

/dev/gpt/dune-root      /               ufs     rw              1       1

/dev/gpt/dune-dune      /dune           ufs     rw              2       2

/dev/gpt/dune-tmp       /tmp            ufs     rw              2       2

/dev/gpt/dune-usr       /usr            ufs     rw              2       2

/dev/gpt/dune-var       /var            ufs     rw              2       2


There may be ways to wire them with CAM, but this is what I've

been using for a long time.
