  // Disable Twig cache (php storage does not exist yet).
  $twig_config = $container->getParameter('twig.config');
  $twig_config['cache'] = FALSE;

  // No service may persist when the early installer kernel is rebooted into
  // the production environment.
  // @todo The DrupalKernel reboot performed by drupal_install_system() is
  //   actually not a "regular" reboot (like ModuleHandler::install()), so
  //   services are not actually persisted.
