I think it has to do with kudzu (the hardware "discovery" tool that
redhat uses). It also "manages" fstab entries for removable devices and
the link in /dev from cdrom to whatever is the device you have (thefstab
entries are marked with the "kudzu" option if they were installed by
kudzu). 

Some time ago the same thing happened to me. I think at that point I
found that /etc/sysconfig/hwconf holds the data for the hardware and
there was a "hdc" there instead of "scd0", I think changing that solved
the problem for me. But at some other point, without me doing anything,
kudzu just erased the fstab entry... So much fun! :-)
