So, thinking about this I first thought that it might make sense to produce several variants, but we don't actually need to do that. Trying to think what people expect from a container:
- people expect it to be minimal (fast to download from the registry)
- people expect they'll be able to install stuff easily in it
- people expect they'll be able to run services easily

(At least that's what I expect from a container. Of course there is a lot more, but these are the most important points for me.) So as long as you can install anything you need inside it and can run stuff there, I think we'll be fine. That means having image that's as minimal as it can get.

Agreed.

Yes, containers shouldn't block releases.

I'll add one more: *How* are we going to test it?

Who's "We"? Cloud SIG? Have you tried talking to Fedora QE to perhaps reuse their infrastructure/hook container tests into it? Do we already some have test cases? What system will we use - Jenkins/something else?

Agreed with both.
