That works on FreeBSD? I commonly use that (daily even) on Linux, but was not
aware that would work on FreeBSD.

Here's the method I use on [modern] FreeBSD:

	mdconfig -a -t vnode -u 99 -f $ISOFILE
	mount -t cd9660 /dev/md99 /mnt

And here's the method I would use on LEGACY FreeBSD:

	cd /dev && sh MAKEDEV vn99
	vnconfig -c vn99 $ISOFILE
	mount -t cd9660 /dev/vn99c /mnt

Or, you can just download this script which works on both Linux and FreeBSD:

http://druidbsd.cvs.sourceforge.net/viewvc/druidbsd/druidbsd/druid/src/tools/mou
nt_iso.sh?view=log

Usage:
	./mount_iso.sh $ISOFILE /mnt

Don't forget that when you're done, you have to deconfigure the device...

On [modern] FreeBSD:

	umount /mnt
	mdconfig -d -u 99

And here's the method for LEGACY FreeBSD:

	umount /mnt
	vnconfig -u vn99c

Or, you can just download this script which works on both Linux and FreeBSD:

http://druidbsd.cvs.sourceforge.net/viewvc/druidbsd/druidbsd/druid/src/tools/umo
unt_iso.sh?view=log

Usage:
	./umount_iso.sh /mnt
