Staying in sync with a stable Ubuntu repo isn't much different then
staying in sync with Linus' tree. However, during the development cycle
the development repo (which is Intrepid right now) is rebased against
Linus' tree which makes life difficult for developers. We'll stop
rebasing around kernel freeze time, which is about late September.
Thereafter everything is a cherry-pick or single commit.
