use vfs.generic.usermount=1 in sysctl

and set user/group privilege to directory to which cd/dvd have to be
mounted like /cdrom

then put in /etc/fstab something like

/dev/cd0a /cdrom cd9660 ro,noauto 0 0


with this - use can do mount /cdrom and umount /cdrom

for raw read - there's no problem to set non-root owner/group for rcd*
