Most of the DHCP clients I have used can be controled by config files and
bound to a specific interface.  You can set directives in the config to
prevent the client from overwriting routes or your resolv.conf.  So when
the machine boots your rc.local could be
  dhcpcd -i eth0 -f /etc/dhcpcd-eth0.conf
  dhcpcd -i eth1 -f /etc/dhcpcd-eth1.conf

Just edit the files for the behavoir you want.  It depends on which distro
your running which dhcpcd you have, or under RH the client is called PUMP.
