[TriLUG] Re: Caching DNS quickstart Was: RR DNS?

Two points here... 

First, you only need the 127.0.0.1 entry in your /etc/resolv.conf - as long 
as your named daemon is running.  The other entries should actually be 
added to your /etc/named.conf file in the "forwarders" section.  I guess 
it's nice to have an alternative if you named daemon breaks down, so its 
cool to put other entries after 127.0.0.1 in your /etc/resolv.conf.

Second, a grep of /etc/network-scripts/* for "resolv" points to "ifup-post" 
as being the source of all know evil in the universe.  Well, perhaps that 
is an exaggeration, but if you want your DHCP app to leave your 
/etc/resolv.conf file alone, you might try editing that file or somehow 
setting the environment variable "$RESOLV_MODS" to "no" (as that tells the 
script not to muck with resolve.conf!).
