Snowfall Lib automatically applies all of your modules to your systems. This means that
all NixOS modules will be imported for your NixOS systems, all Darwin modules will be
imported for your Darwin systems, and all Home Manager modules will be imported for your
Home configurations.
To create a new module, add a new directory to your modules directory.
Now create the Nix file for the module at modules/nixos/my-module/default.nix.
This module will be made available on your flakeās nixosModules, darwinModules,
or homeModules output with the same name as the directory that you created.
