CentOS 8 Stream: Systemd Integration with Podman Containers

Goal

To have a Podman container automatically start, stop, and restart on boot using a systemd unit file generated by podman generate systemd on CentOS 8 Stream.

Constraints & Uncertainty

The generated unit must include proper ExecStart and ExecStop directives, and optional resilience settings like Restart=always. The container may require additional systemd options (e.g., CapabilityBoundingSet) if privileged. Conflicts can arise if podman system service is also running.

Questions

How can I verify that the podman generate systemd output correctly configures the unit to restart the container after a reboot?
What systemd directives should I add to the generated unit to ensure it handles privileged containers without compromising security?
When both systemd and podman system service are enabled, how can I prevent resource conflicts and ensure only one orchestration mechanism controls the container?
