I think that you need some special information in the DHCP server to
get the root path.  My isc dhcp server is configured for that like so:

        host avila.example.com {
                filename "kernel.avila";
                hardware ethernet 00:d0:12:02:76:58;
                fixed-address 192.168.0.10
                option root-path "192.168.0.2:/nfsroots/gateworks";
                option root-opts "nolockd";
        }
