At any rate, make sure your ISP's are locked to a specific ethernet
card. Now you can use iptable/ipchains to route a specific ISP's DNS
server requests out a specific ethernet card. The reason for the dual
resolve.conf files is so when one goes down (call it the primary dns)
you can script a ping test of the upstream gateway for each node and
reset a link to /etc/resolve.conf based on which ISP node has died. Make
the last entry in each file a DNS server from the other ISP so current
queries can still get handled if the node dies during a DNS request.
