#NixOS Update: I've got nearly anything set up. Now I am trying to get #StarCitizen running again. The lug-helper is not usable, because NixOS cannot run "normal" executables. I will now try the flatpak variant and hope it will work.
I still not understand, what the difference between the configuration.nix and flakes is. Are flakes simply module loader? And why are so many NixOS users using Home Manager? What is special about it?
