Config optimizations

[florian-sanders]

Suggested by Claude, these are fairly good actually:

Looking at your configuration, here are several potential improvements:

1. Options Organization: In modules/default.nix, you could move the options to a separate options.nix file since they're becoming quite substantial. This would make the module structure cleaner.

2. Desktop Environment Specialisations: Instead of using lib.mkIf for each desktop environment, you could use specialisations like you did for nvidia/intel. This would make switching between desktop environments more efficient.

3. Hardware Configuration: The hardware configurations for pro and perso are very similar. You could create a common base hardware configuration and only keep the specific differences in the individual files.

4. Shell Aliases: In user/shell-aliases.nix, you could create a function to generate the update/rebuild aliases based on the user specs, as mentioned in your TODO comment:

let
  mkUpdateAliases = username: {
    "upd-${username}" = "nix flake update --flake '${nixosConfigPath}'; nixos-rebuild switch --upgrade --flake '${nixosConfigPath}#${username}' --use-remote-sudo";
    "rebuild-${username}" = "nixos-rebuild switch --flake '${nixosConfigPath}#${username}' --use-remote-sudo";
  };
in

5. Types for User Configuration: Your user configuration could benefit from more structured types:

types.submodule {
  options = {
    name = lib.mkOption {
      type = types.str;
      description = "Username";
    };
    email = lib.mkOption {
      type = types.str;
      description = "User email";
    };
    homeDirectory = lib.mkOption {
      type = types.path;
      description = "User home directory";
    };
  };
}

6. Development Environment: The dev-env.nix could be split into separate modules for different development environments (web, system, etc.).

7. Security Module: Your security settings could be organized by concern (ssh, gpg, clamav, etc.) in separate files.

8. Editor Configurations: The editor configurations (neovim, helix, zed) could be moved to a separate editors subdirectory in packages.

9. Package Categories: In packages/default.nix, you could organize packages into more specific categories using separate files:

{
  imports = [
    ./browsers.nix
    ./development.nix
    ./communication.nix
    ./utilities.nix
    ./editors.nix
    # etc.
  ];
}

10. System Configuration: The system configuration could be organized into more specific domains, similar to the packages suggestion above.
