And here are my words tured into working code:

As you can see here, DHCP client at last obtained an IP from the server. All i need now is to replace that "Running script" with C function configuring the interface (there is no script and will never be, it's just a stub function which just prints parameters with which the script would be called).
I really hope i'll produce a new beta soon.
