Re: "pid 1 does DNS"
That's what I read. Supposing a machine is running TWO network interfaces (eth0 and eth1), perhaps because it's a network guard so has to be a Janus (facing BOTH internally AND externally at the same time, required of a gatekeeper). Then it would make sense that one doesn't want to contaminate each interface's DNS caches with each other since a resolution meant for one network doesn't necessarily apply to the other.
