Urk. Seriously right after I sent the email I saw the /sbin/udhcpc.
Now I just have the problem of how to get it run at startup. By editing
the inittab?

If not using dhcp to set your /etc/resolv.conf file, you get to do that
yourself:
echo "nameserver 999.999.999.999" >/etc/resolv.conf
Naturally, replacing the 9's with the address of your DNS server.
