With a 9 month old, going on 2, in the house, I've been made painfully
aware of the need to have some way to lock the CD-ROM tray. I saw a post
about some patches way back in 1996 to enable user-space control of
this, but haven't seen much in the way of tools to control it.
Is there any straightforward way of disabling the buttons on the CD and
locking all the time? I'm not averse to an ugly hack to 2.4.18+ source
if necessary.
Any suggestions?

Put in a CD and mount it....

I'm not sure exactly what you mean. If there is a CD in the drive and
mounted, the eject button should be software-locked. Do you mean that this
does not happen for you? ...As long as it does, a stupid workaround would
be "leave a CD in the drive mounted all the time".

You could echo "1" >/proc/sys/dev/cdrom/lock
If you do this, even when a cd is *not* in the drive it will be locked.
For information like this, it might be best to open xchat, and head to
openprojects.net and join #linuxhelp. This is a good question, just
perhaps not right for the lkml?

What about the power and reset buttons?

Um, No. My /proc/sys/dev/cdrom/lock defaults to a 1, and the drive opens
when a disc is not present at the touch of the button.

Yeah, the above explanation of 'lock' is wrong. It merely controls
whether the tray should be locked when someone is using the CD-ROM. If
noone is using it, it will still be unlocked. There _is_ a var that
controls permanent locking, however it isn't exported through proc.
You'll have to use the CDROM_LOCKDOOR ioctl.
