This is a great summary. I would like to emphasize the gap here though.
Delorean is building directly from a more or less random git hash. Where
as production is built more traditionally using a release tarball with
some number of cherry-picked patches on top. Thus there is no direct
relationship between what is in delorean current-passed-ci repo and what
is the "production" repo. The delta is likely small when the production
repo gets created at GA, but it is non-zero even then, and just gets
larger as time goes on.
