The "podman generate systemd" command from the article is deprecated. The alternative are Podman Quadlets, which are similar to (docker-)compose.yaml, but defined in systemd unit files.

Is linking to a 404 page meant to highlight the lack of docs, or is there some mistake?
Apparently the documentation was just updated. The new location is
