Where?

To private: after I figured out why the friend class declaration wasn't working
(typo, with no compiler error ... fun).

+  static void Initialize();
+  static void Shutdown();
+ private:
+  friend struct base::DefaultLazyInstanceTraits<
+      chromeos::DeviceOAuth2TokenServiceFactory>;
+
+  DeviceOAuth2TokenServiceFactory();
+  virtual ~DeviceOAuth2TokenServiceFactory();
+
+  DeviceOAuth2TokenService* GetImpl();
+
+  // Called by ChromeBrowserMainPartsChromeOS in order to bootstrap our
+  // DeviceOAuth2TokenService instance after the required global data is
+  // available (local state and request context getter).
+  void InitializeImpl();
+  void ShutdownImpl();
+
+  scoped_ptr<DeviceOAuth2TokenService> device_oauth2_token_service_;
+
+  DISALLOW_COPY_AND_ASSIGN(DeviceOAuth2TokenServiceFactory);
