Sure, I agree that a yum repo is a superior way to deliver updates, but
it won't work the first time, until we reflash with a version that
includes the updater.

Note that the current builds also come with a controversial solution
called "olpc-update", which permits to update the whole system
atomically, using rsync and a forest of hardlinks in /versions. It has
the major flaw of requiring a lot of free space for major updates, but
if you're lucky it may work on most deployed laptops for the simple case
of switching from Dextrose 1 to Dextrose 2. Only a few MBs of packages
have changed.

Sure, automatic updates done in the background are a lot less
"traumatic" for the less technical users.
