This is what we should do, indeed, as a Fuel library team. First, always
get the patch merged upstream, and only next - backport this to Fuel fork.
Ideally, we will next switch to upstream manifests, eventually, so there
would be no need for forks anymore. Sadly, this *never* worked for us
and doesn't work yet as we're, it seems, not ready for this *quite a
long path* of changes landing> So there was a "lazy compromise" and

I strongly believe that someday this will start to work for us. And this
is not just a words of hope. Before we did the first
"get-closer-to-upstream" effort, our fork's code base diverge was ~97%
and 0 patches contributed upstream by changes in Fuel library. An
initial sync with upstream modules was the very first step on the right
way. And we're keep doing the best to reduce the code diverge to be
ready to switch upstream modules one day.

Nothing to add, you are completely right.

Agree, this makes the technical dept only to grow uncontrollable.

I'm all for this option. We have a backlog item to deploy
OpenStack from upstream packages with Fuel. I'd say this must be done by
upstream puppet manifests as well.
