Since there was a complaint about this change, we plan to re-enable TCP ports reuse in future releases. We also ponder making knotd exit if it fails to bind to any of configured TCP ports. We would like hear from you whether such a behaviour is what you, users, want best. Please, let us know if you prefer this or a different solution.
I don't like the idea of the daemon running while not listening to some ports. The situation could go undetected for a while, and lead to an ugly surprise later. I'd prefer to have the daemon fail and exit if it cannot run with the configuration specified.
My opinion of SO_REUSEADDR is that it's fine. Port 53 is privileged, and if something else is listening on it, then the administrator is either aware, or has a bigger problem to deal with anyway.
