this is the exact line in my fstab (i've added the "..." to keep the parts separated in this post):
/dev/cdrom..../mnt/cdrom....iso9660 noauto,owner,kudzu,ro 0 0
mnt/ is where I keep my mount points.
I am using red hat8. my friend did this so i can't say for sure what all that stuff means (and it was a year ago so i forget the details now).
