It works just well right now.
# idig 
example.com @localhost
example.com.            900     IN      A       106.185.25.206
# idig txt chaos version.bind @localhost
version.bind.           0       CH      TXT     "Knot DNS 2.0.0"
I will look further into the documentation, may use knotd to replace
one/more of our BIND servers. We have about 50,000 zones powered by BIND
before. Thanks a lot.

  Perhaps you are running it under upstart or systemd?
Try something like:
 service knot stop
 Cheers, Ondřej

     As you see, both "killall" and "knotc stop" doesn't make the
daemon
     exit, but a new process (with new process ID) appeared.
     Thank you.

         You can change that in the config file - section system (there's
         documentation on the web).
         I'll look into the package since it should be automatic.
