I think this is better for separating modules explicitly. This is also
considered as there are similar objects between modules (e.g., NixOS
and home-manager modules and users).
Revert users module to old position
Welp, that's one step for more convenient and separate user-specific
configuration. It's a tad simpler than
https://github.com/divnix/devos but I want to work my way towards a
similar setup. It's just a little overwhelming starting with that
framework.
