>Description:
	

	Trying to mount an ISO image using the mdconfig_md%d= facility in
	/etc/rc.conf does not work because we do not have a fsck_cd9660
	program.
	
>How-To-Repeat:

	Add to /etc/rc.conf
		mdconfig_md0="-t vnode -o readonly -f /some/image.iso"
	Add to /etc/fstab
		/dev/md0     /cdrom     cd9660  ro,noauto       0       0

	mkdir -p /cdrom

	sh /etc/rc.d/mdconfig2 start
		
>Fix:

	The correct fix is to know if the filesystem can be fsck'ed or not
	but a workaround is to symlink fsck_cd9660 to /usr/bin/true
