When trying to provision MediaWiki-Vagrant after enabling the Phabricator role, a wild error appears:
```

```
What happens is that the manage_config.php script is not found in `../scripts/setup/manage_config.php` because the executing script is located in `/vagrant/srv/phabricator/bin/config`. `..` resolves here to `/vagrant/srv/phabricator/bin`, not `/vagrant/srv/phabricator`, where the script directory is located. `../scripts/setup/manage_config.php` should thus instead be `../../scripts/setup/manage_config.php`.
