alt Hacker NewsQuadlet are great but running podman via systemd as a non root user worked perfectly well before quadlets and I have no idea what your parent is talking about (I'm currently in the process of converting my home services from rootless podman over systemd to quadlet)
Fair, it worked, but podman generate systemd is deprecated now. I found the generated unit files pretty brittle to maintain compared to just having a declarative config that handles the lifecycle.
