The ability to backup $HOME, copy-nand / install-to-a-partition, and
then restore $HOME worked for me when going from 767 -> soas3 ->
fedora-rawhide -> 767 on my XO.  Perhaps if this were a design goal
(or a similar design goal, like "you can move
$HOME/{.sugar,Activities} between sugar versions (which may already be
explicitly supported)) it would suffice for the casual developers
upgrade needs.

I suppose I should think about fancier things, like just mounting
$HOME from an sd card (but then where's the backup, and that races
with X startup at boot) or just treating the XO like any other laptop
and having yum actually runnable (though yum has always been really
prone to OOM on olpc builds, and then we're setting up the unrealistic
expectation that we'd support distro version upgrades) to upgrade
sugar.  ~
