Interesting setup. If you switch to CNID, you could copy the CNID
databases (the stuff in the .AppleDB subdirectory) over to the new
volume in your script as well. Device and inode will be wrong in the
copied database, but the CNID code can correct this automatically to
the new values as files are accessed. You'll have to stop all
active afpd daemons during the copying for this to work, though.

There is an alternative that might be preferable, even considering
your current setup. A Precondition would be that you already use or
would be able to switch over to AFP over TCP/IP, I do not know whether
there is a way to make this work with "pure" Appletalk. You could then
create two instances of the afpd configuration, a regular one and one
that serves the volume read only. The regular one takes care of
your current user "Strider Master", the second instance would be used
to serve the volume read only to "User1 Strider", "User2 Strider" ...

For the two instances to be able to run side by side you would have to
make one of them listen on a different port than the regular AFP TCP
port (548) and also change that in the clients.
