i meant accidentally as hyperbole. The point being if you managed to install arch manually that you had some level of knowledge. Or at least gained it through the experience.

I’d say it’s more like pretending you’re a mechanic while having a fairly comprehensive understanding of how cars work. The difference here is the environment, and the experience. You aren’t gonna become an IT professional unless you’ve had years in the industry or “certification” anyway. But you can certainly roll your own maintenance if you tried.

That is also downplaying a manual install of arch quite a bit, but that’s beyond the point.
