Advise user to close the CD tray if necessary

[Jean Privat]

On the live CD array-5, on shutdown/reboot, the disk is ejected and the computer
ask you to press enter then halt/reboot. Maybe he have to close the cd reader
just after enter is pressed.

[Juanje Ojeda (juanje)]

It depends of the device, but anyway there is a interface to deal with that in
the /proc:
/proc/sys/dev/cdrom/autoclose
/proc/sys/dev/cdrom/lock
/proc/sys/dev/cdrom/autoeject

And there is a eject's option to close:
eject -t
Something like:

And after any cdrom device who is umounted open byself and after, it's suppesed
to close. But of course, that depends fo the device..... not all the devices
support that :(

[Juanje Ojeda (juanje)]

Well, actually the first patch could be simpler as:
<patch-0>

</patch-0>

But I couldn't try. Anyway I think the other way work better, I mean the procfs one.

[Juanje Ojeda (juanje)]

Sorry, I guess I put RESOLVED too soon. I just beliable that those patch resolve
the problem, but I din't wait to somebody else see the patchs and apply them if
they are right.
I reopen it in case someone with rights put the resolution and fix the problem.

Sorry and thanks
