If you question is how does Podman start containers that are
autostarted at boot
Yes, that is exactly what I want to know more about.
then podman has a a podman-restart.service which systemd
automatcially starts, and this service looks at the podman database and
starts any autostart services
/usr/lib/systemd/system/podman-restart.service
/usr/lib/systemd/user/podman-restart.service
Thanks a lot! I will take a closer look when I am on my machine :)
