If you just want a temp filesystem in VM, then mfs is more conveinent.
If you want to use some alternate FS format, or to save the FS image
after it is unmounted, then /dev/rdN lets you do that.

To use /dev/rdN as you would use mfs, you need to:
 	rdconfig /dev/rdNc (blocks) &
	mkfs /dev/rdNc ...
	mount /dev/rdN /mnt
