If we will persist it then we can warn for duplicated, but looks like cloud init is mainly used for one time initialization, so in that case we won't persist it, thus we won't have this information in the engine.

Can you elaborate on that? What would be hard on developers?

We might store those in the engine, allowing users to select one they have permissions on. Not sure we would do it in the first phase, though.

That can indeed be nice.
