[Sugar-devel] Wanting to know a bit of (NetworkManager) workflow upon resume-from-suspend

Another comment from the unwashed:

Years back, I used only ethernet to connect my XOs.  Nowadays, I'm using 
both wired and wireless to connect between XOs.  [By the way, I normally 
run my XOs with suspend disabled - so I have not paid much attention to 
problems associated with 'resume'.]

For about the last year, Network Manager has become "super bossy":

It used to be that if I had an XO on ethernet, Network Manager might 
intervene after some 10+ hours - breaking that ethernet connection.  I 
did not mind occasionally having to "reconnect" the ethernet (I just 
invoke a script that re-issues the necessary commands).

But the current Network Manager intervenes in less than ten SECONDS - it 
breaks the connection on the ethernet (eth1) interface - presumably to 
set up the wireless (eth0) interface (to listen for radio signals).

Bottom line - these days, in order to use ethernet on an XO, I need to 
__disable__ Network Manager.
