> I had _guessed_ that something like the "Building your own installer" section would work, but because of the nature of Nix I never really feel 100% confident that something is gonna work as I hope until I physically try it. Usually it does.
One of the most underrated features of Nix imo is the testing story. You absolutely can be confident that something will work!
Yea I agree on that front. But I don't mean "it's hard to write correct Nix configs" I mean that without a lot of experience it's hard to design a Nix system in your head and know whether the design is naturally supported by the ecosystem or if you're kinda going off into uncharted territory.
It's usually pretty easy to try stuff and I really like the way once you have learned something, you can't ever really forget it because everything is code. I know lots of things say "it's config-as-code!" but very few do hermeticity as well as Nix. In that regard it has some of the benefits of monorepo life, without needing an actual monorepo.
