Open Stack

Last week at the PTG someone asked me about best practices for
changing or deprecating default values for configuration options.
Unfortunately I failed to make any notes at the time and I'm
embarrassed to say that I don't remember who it was or exactly what
the use case was. If that was you, could you let me know?  Another
potentially related case came up, and I think I have an approach
that works for both situations, but before I throw around a lot of
details I want to make sure I've thought it through.
