I do not think this comes from TUV.

It comes from the NetworkManager croud, which I think is the same as
the GNOME croud, or at least they think the same way -
"my laptop^H^H^H^H^H^Htablet is the only use-case that matters".

The normal SL setup (after the installer) is to have "available to all users"
enabled on all system network interfaces and then none of this nonsense happens,
the network functions normally (always enabled).

But I have seen this problem - after the installer, "available to all users" is "off"
and you see the silly behaviour. I discount it as an installer malfunction.
