IF /etc/nsswitch.conf could contain a line like this:

afs: files dns

Not really. It turns out that the innards of the name service switch
are completely different from one operating system to the next, and
not very extensible in this direction. Doing what you describe would
require extending the 'files' and 'dns' nss backends to understand the
"afs" database, which can't be done without replacing the modules the
OS vendor provides (if they're even provided as modules, which is not
required).
Ah, I understand. Thanks for the information. I learned something from it.
Also, a "solution" to what?
I think I choosed the wrong word there. Sorry. "Alternative" would have
been a much better word.
But, what I was trying to say was that with such an alternative (which
you have already explained been hard to implement), AFS could be
configured to ignore CellServDB in favor of AFSDB records (quote ". . .
you can't make AFS ignore the CellServDB in favor of looking up AFSDB
records")
We could probably make it possible to tell the cache manager to use
DNS first, but what would be the point? If you want to rely primarily
on the DNS for locating AFS servers, then your CellServDB should be
mostly empty, containing only entries for cells where the nameservers
are unresponsive, or hand out incorrect data, or where you otherwise
want to override the data handed out in the DNS.
True.
