Jeff, thanks for responding.  The rest of your response (and the
others) made sense and were really helpful.

Regarding the paragraph above, I know what inodes are and the point of
the namei() system call, but I wasn't aware that AFS fileserver
instances came in two "flavors" with these names, or their exact
meaning in this particular context (though I can take a guess).

Can you point me to further documentation on this administrative
decision and its implementation consequences?

Thanks again,
