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.
  foreach ($container->findTaggedServiceIds('persist') as $id => $tags) {
    $definition = $container->getDefinition($id);
    $definition->clearTag('persist');
  }
