The reason you may have been deceived is because you have to set the label on the root (which can only be done in single user when / is RO), then reboot the machine. Even then, /dev/vol/root doesn't show up because GEOM spoils the geom_vol_ffs class instance from /dev/ad0s1a due to an open write on /dev/ad0s1a (which geom_vol_ffs sits on top of). It takes an act of faith to set /dev/vol/root in your /etc/fstab, reboot, and hopefully everything works. -gordon
