        Use a textual configuration file (default is /usr/local/etc/knot/knot.conf).

    -C, --confdb directory
        Use a binary configuration database directory (default is /usr/local/var/lib/knot/confdb). The default configuration database, if exists, has a preference to the default configuration file.

  Options

    -V, --version
        Print the program version. The option -VV makes the program print the compile time configuration summary.

  Signals

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.

EXIT VALUES

Exit status of 0 means successful operation. Any other exit status indicates an error.
