What's the mistake in the directory structure?

nested_route_directory_mistake.js

// app/router.js
Router.map(function() {
  this.route('bacons', function() {
    this.route('bacon', {path: '/:bacon_id'}, function() {
      this.route('aiolis', function() {
        this.route('aioli', {path: '/:aioli_id'}); // Hipsters rejoice.
      });
    });
  });
});

// Directory structure
/*
 * app
 * └── templates
 *     ├── bacons
 *     │   ├── aiolis
 *     │   │   ├── aioli.hbs
 *     │   │   └── index.hbs
 *     │   └── bacon.hbs
 *     └── bacons.hbs
 */

// Aside: I wonder if the actual plural of aioli is aioli. Custom pluraliser?
