This is a sketch of how some of the ideas discussed in the core conversations configuration management sessions yesterday might look in practice. Obviously this is just one idea and there are plenty of other valid approaches (overall of for any specific piece) - we don't want to get too specific yet. For example, some of what I describe could probably happily live in contrib. I think my big picture point is that the approaches discussed are not mutually exclusive, and in fact we probably need bits of each of them.
