 #### Verbose Create Events
 
 Setting `events_container_create_inspect_data=true` in containers.conf(5) instructs Podman to create more verbose container-create events which include a JSON payload with detailed information about the containers.  The JSON payload is identical to the one of podman-container-inspect(1).  The associated field in journald is named `PODMAN_CONTAINER_INSPECT_DATA`.
