I think that we should add a -usedns switch to request the use of dns srv / afsdb records. It should return a failure if the cache manager was not started with afsdb support active. Anyone that is deploying DNS AFSDB records should also deploy DNS SRV records as documented in http://www.rfc-editor.org/rfc/rfc5864.txt as DNS SRV records are superceding AFSDB records in current and future releases of OpenAFS.
