I’ve been considering ownCloud as a solution to provide to thousands of people to be able to just plug in and use. In order for this to work, it needs to be a blackbox that just works. Target is Linux with docker.
Up until the recent change, anyone could then configure their networking outside the box to do any port forwarding, reverse proxy, or whatever to give access to their instance.
If they have to edit any files inside the box, whether that be PHP or YAML, this will not work.
