<p>Whether to enable Nix.</p><p>Disabling this will stop nix-darwin from managing the installed version of Nix, the nix-daemon launchd daemon, and the settings in <span class="mnos-file">/etc/nix/nix.conf</span>.</p><p>This allows you to use nix-darwin without it taking over your system installation of Nix. Some nix-darwin functionality that relies on managing the Nix installation, like the <code>nix.*</code> options to adjust Nix settings or configure a Linux builder, will be unavailable. You will also have to upgrade Nix yourself, as nix-darwin will no longer do so.</p><div class="mnos-warning">If you have already removed your global system installation of Nix, this will break nix-darwin and you will have to reinstall Nix to fix it.</div>
