As I mentioned on one of the other openafs lists, this perl
script is now available for anyone curious about it.  It
assumes that the "full" CellServDB is in 'CellServDB.orig'.
I suspect that many people have written somewhat similar
scripts, although maybe they haven't had the same ideas in
mind as I did when writing this.

I originally intended to have this script also CREATE the
"trimmed-down client CellServDB", but I haven't done that
yet.  It's always been easier to get the initial DB by just
copying a real one and deleting the lines I didn't care about.

If you change the script so the 'is_domain' and 'isin_domain'
arrays were initialized from $ENV, then it could be readily
used as a generic automatic script.  Maybe run it once a day,
to recreate the "trimmed down DB" and refresh the cell-info
for any cells in that list which had changed since the previous
run.  Then add some way for users to see what cells they might
want to add, and a privileged process to add them.  I already
know basically what I want to change in this script to make
all that possible, I just haven't had a big need to do it yet.

Let me know if people would be interested in seeing me add
these things.  I hope to get openafs or ARLA up on my freebsd
boxes soon, and between that and openAFS for MacOS 10, I'll
have a lot more reason to work on these ideas.

Anyway, it's available at:

   ftp://freefour.acs.rpi.edu/pub/openafs/reset_afs_cells

It assumes perl is in /usr/bin/perl, because that's where it
is on MacOS 10...
