With the next version of Podman, podman-generate-systemd ships with a --new flag to generate such portable/shareable service files. However, it does not yet support pods but we are working on it, which is tracked in the upstream issue [1]. > For the case of the pod, what PID does systemd track? Is it the pause > container?

Supporting --new for pods is definitely on our todo-list. Thanks for reaching out. Kind regards, Valentin [1] https://github.com/containers/libpod/issues/4875
