One change you would need to do is to make it listen on 0.0.0.0:53 or the on static IP address of your server. Your clients won't know that they are talking to a different DNS resolver.

I think the parent post is refering to the local domain name, I have 
read this thread and people talk about not touching ever the resolv.conf 
file. What about domain and search lines? If NetworkManager will always 
use 127.0.0.1, it should still modify resolv.conf with the domain name 
received from DHCP
