I have a sparc1+ running 4.1 with a cdrom drive attached to it (only
other peripheral on the scsi bus is the internal disk). While I was
browsing (that means having mounted /dev/sr0 and doing things like
"ls" and "cd" on it) through Vol.1 of the Catalyst cdware, I started to
get lots and lots of messages like:

(open mouth, insert foot.....) I had forgotten to mount the cdrom
read-only.... Mea culpa!
