I see in Drupal documentation about Configuration Management it is adviced to change the location of the
sync directory in a production environnement.
But I can't find an explanation about the actual use of this directory. For what does Drupal use it ? (I expect a more accurate answer than "synchronizing", which I can formulate myself but is not very helping...)
And why is it unadvised to keep this directory accessible from the web ? What could be the consequences ?
