Ah yes, that is of course correct; if no memory disk is in use
yet, /dev/md0 will be the first unit you get, otherwise you can
always specify a custom unit.

You could even use the following, leveraging the fact that mdconfig
will print the partial device name of the unit automatically
assigned - you just need the /dev/ prefix to get the full path:

	# mount -o ro -t cd9660 /dev/`mdconfig -a -t vnode -f example.iso` /mnt

Still, you'd need to find out _which_ unit you've been using so
you can use mdconfig -d with the correct number. ;-)
