Just a question, would we be needing a do-it-yourself explanation of the
steps involved, or are we just going to distribute an image that you
could write to a partition? Both?

I have a XO using a 4gig SD card, started life out as
xo-1-olpc-stream-8.2.1-devel_ext3.img, with the XS repos added, yum
installing xs-pkgs, xs-config now... I've ran into some funny dep issues
but brute forced my way round them. I have some notes around, will try
to add them to the wiki at some point. I've excluded the kernel from
being updated at this point, I'll try a newer kernel at some point
later, just waiting for yum to finish and try rebooting this puppy.
Woohoo reboot time... rats network is broken...  

Time to dig/fix,
