systemd creates the Unix Domain Sockets just once, but duplicates the fds each time the daemon is started. According to systemd descritpion, sd_listen_fds() returns the number of passed file descriptors when it is called for the first time, successive calls return 0. It is then wrong to call again sd_listen_fds() to decide if the socket must be removed, because this call will always return 0 and will constraint SWUpdate to remove the sockets. The effect is that a "systemctl restart swupdate" will lead to a not working SWUpdate, because systemd will still pass the file descriptors, but the socket files were removed by previous run.
