Sudo

Sudo allows a system administrator to delegate authority to give certain users - or groups of users - the ability to run commands as root or another user while providing an audit trail of the commands and their arguments.

Usage

Following simple configuration will allow all users which are part of the group wheel to execute commands specified inside extraRules as super user using sudo without the need to supply a user password.

security.sudo = {
  enable = true;
  extraRules = [{
    commands = [
      {
        command = "${pkgs.systemd}/bin/systemctl suspend";
        options = [ "NOPASSWD" ];
      }
      {
        command = "${pkgs.systemd}/bin/reboot";
        options = [ "NOPASSWD" ];
      }
      {
        command = "${pkgs.systemd}/bin/poweroff";
        options = [ "NOPASSWD" ];
      }
    ];
    groups = [ "wheel" ];
  }];
  extraConfig = with pkgs; ''
    Defaults:picloud secure_path="${lib.makeBinPath [
      systemd
    ]}:/nix/var/nix/profiles/default/bin:/run/current-system/sw/bin"
  '';
};
