Not everyone should use tripleo.sh. My point is that we should move
forward with a common tool, and stop enlarging the gap between tools.
We have created (and are still doing) a technical dept where we have
multiple tools with a ton of overlap, the more we wait, more difficult
it will be to clean this up.

I called quickstart because that's the one I see everyday but my
frustration is about all our tools in general.
I'm actually a OOOQ user and I like this tool, really.
But as you can see, I'm also working on tripleo-ci right now because I
want TripleO CI better and I haven't seen until now some interest to
converge.
James started something cool by trying to deploy an undercloud using
OOOQ from tripleo-ci. That's a start ! We need things like this,
prototyping convergence, and see what we can do.

+1 working in multiple ci systems is painful, I know your pain!

I've been playing around w/ Jame's patch [1] to see if I can help.

I like Jame's approach, I think I may be missing some setup steps that 

nodepool provides.

Gotcha. It was just some examples.

That's something we can try.

My opinion on this is that upstream and downstream CI should only differ on:
* the packages (OSP vs RDO)
* the scenarios (downstream could have customer-specific things)
And that's it. Tools should remain the same IMHO.

I spent the last months working on composable roles and I have now
more time to work on CI; $topic is definitely something where I would
like to help.

woot, I'm excited that you are freeing up and can be more involved!

Thanks as usual Emilien!
