The problem probably lies within restart_udevd() in postinst: "start-stop-daemon --stop --name udevd [...]" will fail, since systemd ships a native udev.service file which doesn't use start-stop-daemon at all. Therefore udevd is still running, and "udevd --daemon" will fail with "error: binding udev control socket"
