My problem with all of those systems is they, by definition, must be very opinionated as to what the base system is. A common counter argument is using various types of “layers” (with differing terminology depending on distro or technology used) but the fact that even for “just” Fedora there are so many bases to choose from shows how that is limited in practice, and slight differences in system preferences makes the “one clean base you can then build from” not as flexible as implied.

I love the idea of them, and definitely recommend them for a new user that doesn’t care what is under the hood, but as soon as you start wanting to change core pieces they start getting more and more in your way, and “rolling back to a clean base” is no longer useful.

I think Nix has the closest ideal to what I would like for myself, but I don’t like the language of its build files and the fact that the recommended way to do things is not the way the official docs describe is too off-putting, so I just run back to my Arch setup. 10 minutes of package selection and installing is more than simple enough for me if I ever need to rebuild and I get to choose exactly what stacks I am using.

I’d rather know what’s going on. Silently working around a problem is how you end up with a system no longer set up the way you think it is.
