I think it does -- but only for a a minute or so.

So far as I can tell, the VPN bit is working just fine.  The sequence
is:

  1 NetworkManager makes wireless connection happen.

  2 Web-page intercept log-in page thingy.  The internet works, and
    resolv.conf is sane.

  3 I start the VPN.  This automatically updates resolv.conf to contain
    the additional entries needed for the VPN.  Internet and VPN both
    work.

  4 (a minute or so later) resolv.conf reverts to that from step 2; VPN
    hostnames can no longer be resolved, which rather breaks it.

  5 I spot that, so copy over resolv.conf with the one from step 3; VPN
    now works properly again.

  6 Go to step 4.

So there isn't anything _extra_ I want to happen or needs scripting; I
just want never to get to step 4!
