Sorry, I'm wrong again: the above line actually sets suitable permission
on /dev/sr0. So the problem is at mount point level. The cdrom is
mounted under /media/CDROM, but whatever permission I give to /media the
CDROM subdirectory is owned by user 1000 and nobody can umount it except
user 1000 (that's me, but if another user mount it, "eject" prompts me
with my own credentials in order to actually eject the CDROM).
I didn't find any way to mount /media/CDROM avoiding this annoying
behaviour.
Deep darkness again.
