[Bug 891121] [NEW] please enable "prepend domain-name-servers 127.0.0.1; "

[Martin-Éric Racine]

Public bug reported:

While investigating ways to always append Google's DNS servers to my
laptop's resolv.conf, I fell upon an Ubuntu Forum thread describing how
uncommenting "prepend domain-name-servers 127.0.0.1;" significantly
improves DNS resolving speed. I tried it and, sure enough, it really
does. Among other things, whereas it used to be hickuppy and slow, Gnash
now runs silky smooth; ditto for any other streaming application. Even
something as simple as "sudo apt-get update" runs smoother and quicker,
once this option has been uncommented.

I was thus wondering whether it could be a good idea to ship
/etc/dhcp/dhclient.conf with this option uncommented by default? Is
there any particular reason why someone would prefer not to enable this
option by default?
