Yesterday I upgraded to Precise and dnsmasq stopped working. That is, DNS queries to localhost were dnsmasq is listening (127.0.0.1) were refused. Removing resolvconf (apt-get remove resolvconf) and rebooting solved the issue (found that suggestion somewhere on Google). /etc/resolv.conf looked fine with and without resolvconf in place. No difference at all. Why would I use resolvconf? Are there any benefits? The Wikipedia article covering resolvconf sucks. Why did resolvconf interfere with dnsmasq? Is this a known issue?
