Config Overlay

Turns the configuration export into an overlay of the shipped configuration of all installed configuration. Installing this module and subsequently exporting configuration will leave only those configuration files in your export directory that have been added or modified relative to the shipped configuration of modules and installation profiles.

Concretely, exporting the configuration of a Standard Drupal installation results in almost 200 files that will usually end up in the Git repository for every single one of your Drupal projects even though the majority of those will never be changed in any way. If this bothers you and you consider this a maintenance burden, then this module is for you! Just installing it will reduce that number to just over 10. As you customize your site and add more configuration this number will grow again, but an additional benefit of this module is if you have multiple sites with similar configuration: just place the common configuration in a shared module (or installation profile) and each config export directory is back to only having configuration specific to that particular site.

Installation

Note that the patch from the core issue "Dispatch config transformation event during site install from configuration" is required for Config Overlay to work during installation of a new site. Depending on your setup, this may be required for the site installation to succeed. Otherwise, a configuration import after the installation may be required to add the configuration that was missed during installation.
