The following link  provides a 'recipe' for using gpart to partition the disk.

If you use the '-L' flag to newfs after creating one or more partitions, e.g.

newfs -L "image" daXp1

This will create a device node in /dev/ufs (/dev/ufs/image).

You may then create fstab  entries as usual, but using the label device, e.g.


/dev/ufs/image		/usr/image		ufs		rw	2 2

Unless you add "noauto" to the options (rw,noauto) the system will
fsck and mount the partition on boot.

You can, of course, create several partitions on the disk, using
a separate label (-L) for each.

Is this what you needed?
