If a module that uses default_content to create some entities is enabled during site install, it will crash during site installation with existing configuration.
I am not sure this is the case for all entities, but I definitely have the issue with files and media.
Create a media that contains a file.
Export to a custom module with default_content.
Have the custom module enabled in your core.extension.yml.
Run a drush site install with exiting configuration:
drush si --existing-config --config-dir=../config/sync -y
Drupal install will crash with an integrity constraint violation, ex:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '8b4eec7f-50e4-48c8-be6e-6869d48a160f' for key 'file_field__uuid__value'
This seems to be linked to hook_modules_installed() being fired twice:
- first during install_bootstrap_full when isConfigSyncing() is still FALSE
- then again in DefaultContentConfigSubscriber::onConfigImport
Do not import content if we are actually in the site install phase (\Drupal\Core\Installer\InstallerKernel::installationAttempted())

Are you sure about this patch working? When I use it, I actually have to check that
\Drupal\Core\Installer\InstallerKernel::installationAttempted()has run, otherwise I continue getting the error for duplicate items.
