Well the summary pretty much says it all, after a fresh install on a machine with a mitsumi fx001D there is no /mnt/cdrom entry in /etc/fstab, while RH was installed from the cdrom.
This is a known issue being moved to the future feature list.
This is still not done in 6.9b4, defered to 7.1 ??
Moving to RESOVLED - DEFERRED from CLOSED - DEFERRED
This hardware requires the user to manually configure it.
