You can use curl (included), or just: rpm -ivh

No need to do this - xs-setup-network will "take over" your network

There was no need to run xs-setup-network again, you could have just
added the WAN connection and rebooted. But no harm in doing so.

The fact that you had no DNS without this rings a bell - am I right in
saying you had the same problem on XS-0.6 on your network without
adding a forwarders entry?

Can you run olpc-log on one of these systems after the crash happens
,and send the output?

Thanks for the detailed testing!
