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).
Also, a "solution" to what? 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.
