stop updating resolv.conf on DHCP

[Florin Andrei]

Multihomed server, external interface on DHCP, internal interfaces with 
fixed addresses. Server is running its own DNS resolver with Bind. So 
there's no need to update resolv.conf via the DHCP client.

I tried this in /etc/network/interfaces:

auto eth2
iface eth2 inet dhcp
dns-nameservers 127.0.0.1
dns-search home.local

But then the DNS servers and domain provided by DHCP are still added to 
resolv.conf in addition to my own. I want to stop that altogether. 
resolv.conf must contain only my own DNS server and domain.

Is there a way to do this nicely, only relying on config scripts, or do 
I have to do it the hard way, modifying system scripts? (which would suck)

I can't believe there's no obvious solution to this simple problem. On 
Red Hat, I would just add PEERDNS=no to the interface config and the 
problem would be solved. :(
