[magnusnordlander]

Following the installation instructions in the best practices document, it is impossible to create the AppBundle as suggested in the side note. To wit:

  [InvalidArgumentException]                                                   
  The namespace must contain a vendor namespace (e.g. "VendorName\AppBundle"   
  instead of simply "AppBundle").                                              
  If you've specified a vendor namespace, did you forget to surround it with   
  quotes (init:bundle "Acme\BlogBundle")?

@magnusnordlander thanks for reporting this error. You are absolutely right, it doesn't work right now.

Fortunately, there is a PR about to be merged that fixes this: https://github.com/sensiolabs/SensioGeneratorBundle/pull/299

Moreover, when 2.6 is launched, the process that you've showed in your PR will be as follows:

$ symfony new blog

That's all! The latest version of Symfony will be downloaded and the AppBundle will be already generated and loaded.

Closing this. The guide is still in beta and it'll start working when 2.6 is released. Thanks for reporting. I'm sorry that it is a bit unclear and it gives you wrong information at the moment.

[magnusnordlander]

Well, the instructions were specific to Symfony <=2.5, but yes, that GeneratorBundle PR will certainly fix it :)
