Infrastructure

For the latest version of core that will get installed, I'm wondering if that is the GA release of core or the nightly. Yesterday when we were talking I suggested using the nightly, but now I'm thinking that the existing GA is probably the best. The reason you would want it to be the nightly is because of situations wituations where plugin code relies on core changes that are not part of the GA release yet. The reason not to use nightlies is that they could be unreliable. I'm favoring using the GA for two reasons:

1. plugin code changes on the pulp2 line that also require unreleased core changes doesn't happen a whole lot (but some).

2. It's probably a best practice to test one thing at a time. This is about testing the plugin code, so that means core should be stable. If we use the nightly for most failures we'll have to determine if platform OR the plugin code is broken. By always using the GA of core we know everytime that it's the plugin. It's also possible that the plugin needs not-yet-released code in core, but the plugin writer should know if they are in one of those cases at which point tests can be run locally to prove they work perhaps.

What do others think about ^?
