[K12OSN] allowing users to write to CDs in server

[Petre Scheie]

How do I allow users to write to the CD-burner in the server?  Nautilus 
has a 'CD/DVD creator' under the Places menu, but when a regular user 
then selects 'Write to disk' under the file menu, it just keeps asking 
for a disk in the CD drive even though there's already one there.  I 
changed the permissions to setuid for root for /usr/bin/cdrecord, but to 
no avail.  If I log in as root, it works, but the uses want to be able 
create their own CDs.  (These are all adults so I'm not worried about 
them behaving themselves.)
