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.
