Draft: Forbid adding custom modules to new Drupal websites
After the ED meeting, we can now start by blocking Drupal websites from installing modules that are not in the cern-drupal-distribution.
There are many considerations to take into account:
- Can only affect new instances
- Drupal does not seem to have any easy locking/disabling of the installation button (maybe a custom development might be required and added to the installation page)
- Filesystem lock on the image might affect existing websites
