[Dnsmasq-discuss] How to add local configuration to Network Manager initiated dnsmasq in Ubuntu 12.04

[Niall Litchfield]

Did you come across Stephane Graber's website and article at
http://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/ (not sure if
Stephane is on this list). If what you are after is just nameserver changes
he addresses that. Now I'll admit to disabling the network manager install
of dnsmasq and installing my own installation instead for 2 reasons


   - like you I couldn't find a documented sensible way to customize
   dnsmasq supplied with Ubuntu - the design goal seems to be to limit you to
   the network manager interface
   - I like playing :)
