It can be more resource efficient to start a unix:scoket in case of hiding cloud-torrent behind nginx web server. I have not found such an option in documentation. I guess it should be technically possible to implement functionality of starting unix:socket

since ver 1.3.0

use --host=unix://run/cld.sock, or the env variable HOST=unix://run/cld.sock to listen on unix socket
