During the recent Verisign debacle I installed dnsmasq.  I made the 
following change to /etc/dhclient-script:

make_resolv_conf() {
  echo search $new_domain_name >/etc/resolv-up.conf
  echo search $new_domain_name >/etc/resolv.conf
  for nameserver in $new_domain_name_servers; do
    echo nameserver $nameserver >>/etc/resolv-up.conf # <<- here
  done
  echo nameserver 127.0.0.1 >>/etc/resolv.conf  ## <<<- here
}

This way I get dns-caching, which otherwise I think the upstream DNS 
server is queried for every DNS request, which would suck over dialup.

Is this correct?
