Comment 7 for bug 922677

Yeah, currently Ubuntu's rule is "/sbin/resolvconf exists" and "/etc/resolv.conf is a symlink". We don't really check where the symlink points to even though I guess we should :)

We made resolvconf a hard depend of ubuntu-minimal which means it gets on any system we can call an Ubuntu system and is part of the basic set of packages that get installed by debootstrap. So removing it isn't really an option as that'd mean uninstall ubuntu-minimal which is usually a bad idea.

Manually changing the answer in debconf would work, though the current priority makes it an invisible option that won't prompt at install (we don't want it to prompt anyway).
So people would have to replace /etc/resolv.conf by a file and make sure they change the debconf value, which would work but isn't necessarily obvious to our users.

Making it immutable would very likely cause a few more problems from other tools trying to touch /etc/resolv.conf so that doesn't really sound like a solution either.
