Comment 3 for bug 1305156

Thanks for the quick reply! dbndnscache doesn't come with an init script AFAICT. I also did not see any code in the update.d/dnscache to ignore existing dnscache addresses, but I may have missed it

So if I understand correctly, the right thing to do would be to add the dnscache address to /etc/resolvconf/resolv.conf.d/base and *not* include the dnscache address under dns-nameservers in /etc/network/interfaces.

I switched the package to dbndns since that's the one I'm actually using.
