I noticed that Stephen Parrish had removed olpc-update from F11-XO1,
which made /versions also superfluous. Besides the nice saving in space,
disabling the versioned fs considerably sped up olpc-os-builder.

Hmmm... perhaps I should reconsider this decision. We'd first have to do
some testing to ensure your original work still works well with F11-XO1.

Last time I looked, the hostname of the update server was hardcoded
inside olpc-update. Did you create a custom package to point it at the

For a future release cycle, we may want to re-evaluate yum-updatesd as
an alternative to olpc-updates which provides different trade-offs in
terms of performance, robustness and distro integration. At the time
olpc-update was written, yum was still awfully buggy and unreliable.
