NixOS, makes it easy to have the same setup because it’s all in one config file. I didn’t check it out until last year when they released a graphical installer, now installing/using NixOS is a breeze.

Even if I didn’t install NixOS, I’d use the Nix package manager (which is separate, but part of a NixOS system) since it has more packages than the AUR. It’s easy to contribute to, so I’ve been maintaining a package.
