+1 Using packages solves some problems very nicely. We haven't solved all the CI related issues around using packages with upstream but it is getting better. I mention this because it would be nice to have CI testing on the upgrade process automated at some point... > > HA - We have an implementation of HA in tripleo-image-elements today. > However, the Puppet codepath leaves that mostly unused. The Puppet > modules however do support HA. Is that the answer here as well? In general most of the puppet modules support the required HA bits. We are still working to integrate some of the final pieces here but in general I expect this to proceed quickly. > > CLI - We have devtest.

I think this is an interesting idea and perhaps has some merit. I'd like to see some specific examples showing how the unified CLI might make things easier for end users... > > Baremetal management - To what extent should TripleO venture into this > space?

And also should we think about possibly renaming these? I find that many times when talking about TripleO to someone new they find the whole undercloud/overcloud thing confusing. Calling the undercloud the "baremetal cloud" makes it click. > > Release Cadence with wider OpenStack - I'd love to be able to say on > the day that a new release of OpenStack goes live that you can use > TripleO to deploy that release in production...and here's how you'd do > it.... > > What other items should we include here?
