You're right: the saving in space is just 5MB (compressed). The build
time overhead is about 2 minutes on a total runtime of 13 minutes;
bearable even for the impatient buildmaster :-)

I had to pull your recent additions to olpc-os-builder and rebase my
changes on top of it. The new modules open the opportunity for me to
cleanup a few kludges, but I'm afraid of changing too many things just 3
days before release.

I'd say this is still working fine, because laptops perform activation
from wifi just after being flashed with the new OS. Is there anything
else I should check for? I have very little understanding of the
internals of OATS.

Interesting. Do you remember the subject?
