I'm afraid that olpc-update will never become usable in the general
case. I find it hard to believe that users will be willing to sacrifice
~500MB of their flash to accommodate updates. In the field, it's a lot
faster to flash a new image from USB and then restore the journal from
backup.

Today I found out that Esteban, a Ceibal developer, has been working on
a "backup to USB" patch for the Journal.

In Paraguay, we've been using two simple shell scripts to save and
restore the journal across upgrades, but a proper UI would definitely
simplify things for the technicians.
