You might wish to read the "vnconfig" man-page , a small
extract of which follows:

Configure a CD-ROM or DVD image file as vnode disk svnd0 and mount the
ISO 9660 file system contained in it:

# vnconfig svnd0 /tmp/diskimage
# mount -t cd9660 /dev/svnd0c /mnt


Unmount the file system and unconfigure the vnode device:

# umount /mnt
# vnconfig -u svnd0 [...]
