We had issues with Nextcloud when restarting our VMs where the permissions on the root path of the nextdata volume got changed to the root user.

While the core issue probably lays in our system update routine, ensuring the correct access to the root directory (not recursively) would make the app itself more resilient against this.

Example solution in wordpress:

wordpress/entrypoint.sh.tmpl Line 57 in fadb247d47
chown -R --from=root:root www-data:www-data /var/www/html/wp-content/

Proposal to add:

chown --from=root:root www-data:www-data /var/www/html/data/

Looks safe to add this. Was it only the nextdata that was changed? Or also other volumes where maybe it did not directly cause an issue?
