An important principle of troubleshooting is that no conclusions can
be drawn from a singular event. If you had said, ""find" works over
other CD's, but still not with the CD that I burned myself", it would
have made all the difference, in my mind.

I was also confused by your calling your mountpoint "/mnt/cd0".
Although you're free to make directories and mount things anywhere you
like, "/mnt" itself is usually used as the mountpoint, especially for
exposition (see hier(7)). My problem, not yours.

Thanks for the excellent followup!  I still have a couple of
questions, if you don't mind...

1) On the bad CD, what does "ls <mountpoint>" and "cd <mountpoint>;
ls; cd <somedir>; ls; find" give? In other words, is the CD apparently
empty by all accounts, or is it really only a problem with "find" on
the mountpoint?

2) What _is_ the wrong way to burn a CD on NetBSD? The right way?
