In Debian, with isc-dhcp-client, there are directories like 
/etc/dhcp/dhclient-enter-hooks.d that are processed by 
/sbin/dhclient-script.  You can override the DHCP variables 
(new_domain_name, new_domain_search, new_domain_name_servers) and 
functions by setting them in a new file named 
/etc/dhcp/dhclient-enter-hooks.d/resolv-override for example.  See the 
make_resolv_conf function in /sbin/dhclient-script.  In my case, I don't 
need my resolv.conf changed, so I copied the make_resolv_conf function 
to /etc/dhcp/dhclient-enter-hooks.d/protect-resolv-conf and commented 
out the final mv that overwrites /etc/resolv.conf.
