 If you want to modify service definitions of another bundle, you can use a compiler
 pass to change the class of the service or to modify method calls. In the following
 example, the implementing class for the ``original-service-id`` is changed to
-``Acme\DemoBundle\YourService``::
+``App\YourService``::
 
-    // src/Acme/DemoBundle/DependencyInjection/Compiler/OverrideServiceCompilerPass.php
-    namespace Acme\DemoBundle\DependencyInjection\Compiler;
+    // src/Kernel.php
+    namespace App;
 
-    use Acme\DemoBundle\YourService;
-    use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
+    use App\Service\YourService;
     use Symfony\Component\DependencyInjection\ContainerBuilder;
 
-    class OverrideServiceCompilerPass implements CompilerPassInterface
+    class Kernel extends BaseKernel
     {
         public function process(ContainerBuilder $container)
         {
-            $definition = $container->getDefinition('original-service-id');
+            $definition = $container->findDefinition('original-service-id');
             $definition->setClass(YourService::class);
         }
     }
