mounted cd and tray locking

[Andriy Gapon]

I recently noticed that FreeBSD doesn't prevent tray opening (via a
button on CD/DVD drive) even if I mount a CD with ISO 9660 filesystem on
it. This at least happens with ATAPI CD drive (acd driver/device).

Maybe my memory is failing me but I seem to remember times when mounting
a CD locked a tray. Shouldn't this be a more reasonable behavior ?

Also, I think that it would be good if tray got locked on opening a
cd/acd device (e.g. dd if=/dev/acd0).

BTW, my system is 6.2.
