Code

public function alter(ContainerBuilder $container) {
    // Disable Twig cache (php storage does not exist yet).
    $twig_config = $container->getParameter('twig.config');
    $twig_config['cache'] = FALSE;
    $container->setParameter('twig.config', $twig_config);
    // 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 ModuleInstaller::install()), so
    //   services are not actually persisted.
