Architecture overview diagram misleading

[schlessera]

The overview diagram in the architecture index looks to me like it is the wrong way around.

From the diagram, I'd deduce that the operating system is this large thing that includes the supervisor and the core, and the supervisor is a smaller part of the operating system that includes the core, and finally the core is is indepedent thing that is at the very heart of the operating system.

However, technically, it should be the other way around, with the operating system being the fundamental smallest piece, and the supervisor being a superset of the operating system, and the core again being a superset of the supervisor.

But the core is actually independent from the supervisor and the supervisor is independent from the OS. Both can be used without its superset.

Maybe I'm just misunderstanding here... What type of relationship is meant to be portrayed with the diagram?

1. what requires what?
2. what is built on top of what?
3. what is running on top of what?
4. what functionality includes what functionality?

I assume you'll get different diagrams depending on what you're trying to express. I personally had trouble reconciling the diagram with the text preceding it, but maybe this is just my mental model gone wrong.
