See 'pinfo mount', 'pinfo fstab' for options available. You 
might be able to make the CD/DVD drive ro, with something 
like this in your /etc fstab file:

# DVD-RW drive VOM-12E48X - Fedora 12 example
/dev/sr0   /media/dvdrecorder  iso9660 ro,user,noauto,unhide  0 0
>From the mount(8) man page:
The non-superuser mounts.
Normally,  only  the superuser can mount filesystems.  However,
when fstab contains the user option on a line, anybody can
mount the corresponding system.

Thus, given a line

     /dev/cdrom  /cd  iso9660 ro,user,noauto,unhide

any  user  can  mount the iso9660 filesystem found on his CDROM
using the command

   mount /dev/cdrom

or

   mount /cd
