nix/guix can be used on any distro and it provides a way to organize .config files so that if the .config directory gets deleted or accidentally modified for some reason, restoring it would be very easy. By putting the configuration in a git repo, it also makes it easy to restore previous configurations. I accidentally deleted a bunch of stuff in my .config directory once and that’s one of the reason I use this tooling now, so I thought OP would find it helpful also
