It will depend on the DHCP client you use, of course, but all my OSes
have standardized on ISC's dhclient.  In that case, it's a matter of
editing /etc/dhclient.conf (or /etc/dhcp3/dhclient.conf) and making use
of the following or similar lines:

supersede domain-name "example.com";
prepend domain-name-servers 127.0.0.1;

I think you can use supersede, prepend, and append for any of the above,
but the documentation can tell you for sure.
