/etc/dhclient.conf syntax?

[Gerard Samuel]

I cant seem to get a custom version of /etc/resolv.conf to stick.
dhclient keeps overwriting it with data from my ISP's dhcp server.
This is what I have in /etc/dhclient.conf ->
interface "ed0" {
    supercede domain-name "trini0.org";
    prepend domain-name-servers 127.0.0.1;
}

And for some reason, /etc/resolv.conf *always* comes back as ->
search some_name.attbi.com
nameserver www.xxx.yyy.zzz
nameserver www.xxx.yyy.zzz

Is there anyway to make /etc/resolv.conf stick??
Thanks
