The "auto/noauto" option is used to tell `mount -a` if the filesystem should
be mounted automatically.  The typical line for a CD/DVD device that isn't
needed at boot is something like:

/dev/device			/mountpoint		cd9660	ro,noauto

It's not, you should use "ro" for CD/DVD drives.  The mounted filesystems on
these drives can't be written to even if the media itself is writeable.  In
FreeBSD, CD/DVD writing is done by writing directly to the device.
