Problem/Motivation
As a user I want to be able to install Drupal from a package of configuration that is maintained in git.
At DrupalCon New Orleans, a workflow was discussed that would allow a profile would contain the config sync directory and this full config export should be used at install time. T
Proposed resolution
If a install profile contains a config/sync directory this will be use to install the site.
To create an install profile that works this way on an existing site you can use https://www.drupal.org/project/install_profile_generator
To be clear, this issue would only pertain to install profiles. The separate use case of allowing a site to be installed from an existing configuration export which is not part of a profile is covered in #1613424: Allow a site to be installed from existing configuration.
Remaining tasks
Add config validation
Add more test coverage
