After you've rebased the Ubuntu tags no longer make sense 'cause the
commits that they referenced are likely gone. We try to follow the
protocol of adding the tag name in the commit message atr the time the
tag was created, e.g., Ubuntu-2.6.25-7.1. That way if you ever want to
re-create the tag you can do it from the new commit SHA1.
