stitch will just make the pseudomerge for you, giving you a
fast-forwarding branch suitable for pushing to salsa or whereever.
-There is one caveat I should mention: right now, if two git-debrebase
-branches diverge, it is not trivial to merge them again. If
-git-debrebase encounters a normal `git merge' it will stop and fail.
-Sorting this out is not a trivial problem. gbp pq sometimes handles
-this kind of situation by expecting you to merge the actual patches:
-ie, you can end up resolving merge conflicts in diffs. The other
-tools can handle this badly too.
-
-I have ideas about how to do better at this, so watch this space.
-But, for now, avoid allowing your git-debrebase branch to diverge.
-git-debrebase will help you with that by often spotting when it is
-about to occur.

===== data model slide merge conflict failure
-What if you have a merge conflict during the upstream rebase ?
+More common is a different kind of merge problem.
+
+What happens if you one of your delta queue commits doesn't apply
+during the upstream rebase ?
git-rebase users will have seen this kind of situation before.
git-rebase stops at the first commit which can't be applied in
discarded, leaving you just where you were before. You've wasted no
effort because everything you're throwing away was machine-made.
+===== data model slide [5] AGAIN
+
+There is one caveat I should mention:
+
+Right now, if two git-debrebase branches diverge, it is not trivial to
+merge them again. The data model I'm describing does not currently
+allow general merge commits.
+
+If git-debrebase encounters a normal `git merge' it will stop and
+fail. In the general case, sorting out such a merge is not a trivial
+problem.

+gbp pq sometimes handles this kind of situation by expecting you to
+merge the actual patches: ie, you can end up resolving merge conflicts
+in diffs. Other tools don't always handle this well either.
+
+I have ideas about how to do better at this, so watch this space.
+But, for now, teams should coordinate to avoid creating diverging
+git-debrebase branches. git-debrebase will help you with that by
+often spotting when it is about to occur.

===== status and references slide
git-debrebase is available in testing and stretch-backports and is in
is comprehensive.
No doubt the user interface and documentation will improve, and new
-features will will be added, but you can start using it right away.
+features will will be added. But you can start using it right away.
The best starting point is probably the tutorial manpage
dgit-maint-debrebase (7) (which is in the dgit package).
