* Installs the default configuration of a given extension.

* directories for all other extensions to locate any configuration with its

* default configuration file:
* core/modules/node/config/views.view.frontpage.yml
* When the Views module is installed after the Node module is already enabled,
* the frontpage view will be installed.

* installed is searched to discover if it contains default configuration
* that is owned by other enabled extensions. So, the frontpage view will also
* be installed when the Node module is installed after Views.
