Currently systemd has no insight into the startup state of the seatd server process, so it might start dependant services too early, causing them to fail due to being unable to connect to seatd.
Use the readyfd2sd adapter to convert the seatd s6 ready notification to systemd-notify and switch the service to the notify type to allow systemd to defer dependant service startup until seatd is ready to accept requests.
