Rootless container thoughts

[Apollo3zehn]

With podman it seems we have to ways to run rootless:

• Either use a non-root user in the container and start it as root in the host system
• Or run systemd service as specific user and then this user has root access in the container but non-root in the host ("user namespaces")

For this we need a data folder accessible by the non-root user which is now ~/.local/share/nexus/xxx.

But is this a good idea? To put together all kind of data? Previously settings.json was located under /etc/nexus because it is a settings file for Nexus itself, not for Nexus's content.
