AFAIK the only command that uses fstab is mount, which reads it every time
it runs. I've added entries before and just used them, so it is safe. But
there is nothing wrong with being careful either.

Ok... Did you create /mnt/cdrom2? You have to create the directory that
you want to mount the device on. It sounds to me like that is the problem.

All the timeout and "trying harder" business doesn't sound too good to me,
but since it only does it the first time I suspect that it will work fine.

Order in /etc/fstab shouldn't matter, and neither should the order on the
SCSI bus.
