You also need a customized dhclient-script, which talks to dhcdbd back with
dbus. In my script I have the following (taken from gentoo)

if [ -n "${dhc_dbus}" ]; then
   /usr/bin/dbus-send \
       --system \
       --dest=com.redhat.dhcp \
       --type=method_call \
       /com/redhat/dhcp/$interface \
       com.redhat.dhcp.set \
       'string:'"`env | /bin/egrep -v '^(PATH|SHLVL|_|PWD|dhc_dbus)\='`";
       if (( ( dhc_dbus & 31 ) == 31 )); then
           exit 0;
       fi;
fi;
