For the other part, if you're running your own nameserver, why would you want to use forwarders at all? The only way to change the bind settings would be through a script that does it. But I don't think you could run it from dhclient, as there's no way I know of to pass the retrieved name server information to a script. Possibly write a script that requests the name server data from the DHCP server independent of dhclient, and update the bind config from there. Alex.
