I think it can be reduced to a single manifest per node.
Also, when a review is created it would be easier to check if you create one
review for the python, puppet, tests and release notes.

I would like to have packstack to be multi node since the requirements for
TripleO are still to big for PoC.

Does it make sense to convert packstack to an ansible module?

I started a refactor [1] as part of a manifest cleanup, unifcation and to
start de refactor discussion, i'm happy that Javier took the puppet-openstack-integration
road.
Another idea around this refactor is to make packstack create manifests
that can be used even without packstack runs, installing them in the proper puppet
environment directories and setting the OPM path as part of the this OpenStack? environment,
thus making packstack a puppet manifest generator...

Cheers,
Ivan
