Hi Anna,
Great write-up. Just wondering if you had a chance to run the /var off
a external USB drive on the XS-on-XO (like we had at the OLPC SF
summit). By the way, Ben Tran has defended his thesis project
successfully (http://file.status.net/i/identica/sameerverma-20101215T220215-6bczm4g.jpeg),
so we should start seeing his documents, tests and results on the wiki
sometime soon.

cheers,
Sameer
