I don't have this problem.

looks fine and very similar to my setup.

Okay, I've worked it out (I think) you have /dev/cdrom as a symlink to
/dev/sbpcd right?

Either change the entry in /etc/fstab to be sbpcd or make cdrom a proper
device special file not a symlink. The other thing that may be a bit
wrong is specifying defaults and then other params, you generally do one
or the other (although doing both is correct, just a wee bit weird)

Here's my setup FYI.


/dev/hdb1 / ext2 defaults 1 1
/boot/swap swap swap defaults 0 0
/dev/hdb3 /usr ext2 defaults 1 2
/dev/hdb4 /usr/local ext2 defaults 1 3
none /proc proc defaults 0 0
/dev/hda1 /dos msdos noauto,user 1 0
/dev/cdrom /cdrom iso9660 noauto,user,ro 0 0
/dev/cdrom /cdrom/sunsite iso9660 noauto,user,ro 0 0
/dev/cdrom /cdrom/slackware iso9660 noauto,user,ro 0 0
/dev/cdrom /cdrom/disk3 iso9660 noauto,user,ro 0 0
/dev/cdrom /cdrom/disk4 iso9660 noauto,user,ro 0 0
/dev/fd0 /mnt msdos noauto,user 0 0


brw-r--r-- 1 root root 25, 0 Feb 2 22:54 /dev/cdrom
