[Podman] logging through up to host / systemd init container

I wonder whats the current best approach for having the logs of one container accumulated at the host layer (journald). The container runs systemd/journald and is started via a quadlet config with LogDriver=passthrough. So, everything that the container spells out via stderr/stdout is captured at the host layer. How to pass everything of the container journald to the host journald? I played with LogTarget in /etc/systemd/system.conf without success. I'd really appreciate any ideas! -- Leon
