Comment:

 I can confirm this in a similar, but not identical scenario.

 I have a B4 XO-1 loaded with OS8, the latest build from the F11 on XO-1
 project.

 I've set up an ad-hoc network from my Ubuntu laptop with NetworkManager.
 It's got no encryption and is set for Internet Connection Sharing.
  When I connect to it with the XO (from within Sugar - Neighbourhood), it
 succeds but ifconfig reveals that it get configured with ip 10.42.43.1
 (which is the same address as my Ubuntu box - duplicate), no default
 gateway -> no internet. If I issue:
      dhclient eth0
 it then gets the correct ip and is able to connect to the internet and
 all.
 This does not happen if I connect using NetworkManager within GNOME. Also,
 I can connect correctly to Access Points from Neighbourhood (it gets the
 correct settings assigned), it seems to be an issue just with ad-hoc
 networks.

 Fix:
 Call dhclient after each connection to an ad-hoc network.

 Why are ad-hoc networks important?
 There are no access points nearby. My router doesn't have wireless. An ad-
 hoc network with Internet Sharing is the only option to connect my XO to
 the internet at home. I suppose I'm not the only one in this situation.
