Yeah, I reached the same conclusion independantly.

The problem in the context of Debian is that we're taking previously
working systems that happen to search local, and breaking them by
auto-enabling mdns. I agree that if a user has a working system that
uses madns and adds "search local" to it, it's not a big deal when it
starts being slow and/or breaking[1]. But this is a bit different, and
seems to at least need to be fixed in the context of the Debian package.

One option would be for the Debian package to warn about this at
install/upgrade time, and either remove the search local, or remove the
nsswitch.conf entries.

[1] Although I'm using mdns so much now that it would be nice to be able
    to do that. Typing ".local" gets old. :-)
