DNS resolver changes in Ubuntu Precise (12.04)

One of the first things that irked me after my Precise installation was how DNS suddenly seemed slow. I normally use dnscache for local DNS caching and while setting it up this time, I noticed that oddly, was already setup as my name server. Netstat told me that this was handled by DNSMasq for some reason. No worries, I thought, and I setup dnscache on instead. I added the IP to the prepend nameserver option in /etc/dhcp/dhclient.
