Two things come to mind:

• A saying attributed to Eistein: "Everything should be made as simple as possible, but not any simpler"
• This brilliant Richard Feynnman's interview clip: https://www.youtube.com/watch?v=36GT2zI8lVA

An admin who cannot run an upgrade via a ready-made playbook is bound to a world of pain.
I am not trying to dissuade anyone from hosting an instance.
I am trying to suggest learning the fundamentals first; it will become invaluable in the near future.

And maybe there needs to just be a straight up message saying "self hosting lemmy is not for self-hosters, it is for developers, as there is no documentation and there are assumptions that you will just know how everything works"
