Overwrite DS.Store ember-cli - ember.js

Question

I have some code that needs to run on store.init.
I tried extending the default store in app/store.js, ember-cli seems to pick it up as a store, but the object in this.store is not a store
My store definition:
import DS from 'ember-data';
export default DS.Store.extend({
init:function(){
console.log('watatLoL')
}
});

According to Peter Wagenet, this has changed in Ember Data beta 19. If you're using that version or later, the file is now app/stores/application.js (or app/application/store.js if you're using pods).
Overwriting the store is the same, only the file name/location has changed. If you're using a version of Ember Data lower than beta 19, you can use the old app/store.js file.
I know this is old, but I had to answer this for another question, so I figured I would update this. By default, the Ember-CLI resolver will look for app/store.js, so you can declare your overridden store there.
// app/store.js
import DS from 'ember-data';
export default DS.Store.extend({
init: function() {
console.log('Using custom store!');
return this._super.apply(this, arguments);
}
});

The answer for > Ember 1.13:
The Store now extends the Service so we can just create the app/services/store.js and put the following code to extend/customize the store:
// app/services/store.js
import DS from 'ember-data';
export default DS.Store.extend({
init: function() {
console.log('Using custom store!');
return this._super.apply(this, arguments);
}
});
