For this hint in the code: https://github.com/nextcloud/server/blob/c39a14ee507b8f5f2e06d44b01666c98d5b29c42/lib/private/legacy/util.php#L756-L759 There is no information at the corresponding site of the documentation: https://docs.nextcloud.com/server/14/admin_manual/installation/installation_wizard.html#setting-strong-directory-permissions Can we have a check, if the references in the code still link to an existing point in the documentation?
