One thing that I think we should be verifying is that the changes being
brought over have actually been committed to oslo-incubator. I'm sure there
have been times where someone eager to get the fix in has not waited for
the oslo-incubator merge before syncing their change over.

When I sync a change from oslo-incubator to fix a bug I put Closes-Bug on
the commit message to indicate what bug is being fixed. If the sync tool
was enhanced to pick out the *-Bug references from the oslo commits to
include in the sync commit message that would be handy.

How does one get the list of commits that are being brought over from
oslo-incubator? You'd have to know what the previous commit was that was
