Set maximum size of the configuration database (default is @conf_mapsize@ MiB, maximum 10000 MiB).
-s, --socket path

If the knotd process receives a SIGHUP signal, it reloads its configuration and reopens the log files, if they are configured. When knotd receives a SIGUSR1 signal, it reloads all configured zones. Upon receiving a SIGINT signal, knotd exits.
