Yes, this is very true.  The context in my mind included the
not-present-above phrase "in production".

I hear this too, and do not want to discourage those use cases.  However,
there is little real guidance on what parts of DevStack are representative
of a production deployment and what parts should not be replicated.
DevStack's use of sudo, for example, is one of those places that would be a
huge security issue in any real deployment.

So I would be interested in hearing ideas on this topic.  One of the
reasons DevStack is (still) written in shell script is that we always felt
it was easier to demonstrate how the pieces fit together that way.
