I had a similar problem. First make sure you can mount the CD-RW manually. I
think the installer is smart enough to determine the drive is CD-RW, so it
sets up the SCSI emulation for you. It just doesn't change fstab to reflect
this. Try (assuming you want to mount it on /mnt/cdrom2):
mount -t iso9660 /dev/scd0 /mnt/cdrom2
You may have unmount /mnt/cdrom2 first. If this works, change the following
line (again assuming fstab is trying to mount your CD-RW on
/mnt/cdrom2/):
mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/cdrom2 0 0
to:
/mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/scd0 0 0
You are changing the "dev=" portion to point at "/dev/scd0".
Hope this helps.
