GEOM_LABEL is what you're looking for. Check the glabel(8) man
page. In a nutshell, you'd do this:
tunefs -L log /dev/ad1s1a
tunefs -L db /dev/da4s1a
tunefs -L www /dev/da4s1a
...
mount /dev/ufs/log /mnt/log
mount /dev/ufs/db /mnt/db
mount /dev/ufs/www /mnt/www
(you get the idea). Obviously you can move use the /dev/ufs/*
devices in fstab as well.
If later on you move the filesystems to a different device while
retaining the label (which means no tar, you have to use dd or
dump/restore), everything works.
Hope it helps. Bye,
Andrea
