Thank you for the information.
Is fork still to be an experimental parameter?

As it is commonly used, it is not mandatory as myself, so for the moment I think whether to deal with the parameter removed.

Best regards.

I don't immediately see what happens in your case, but so far kresd does not support running under systemd supervision with multiple forks. It's actually supposed to print a descriptive error and exit if that configuration is detected. See also https://gitlab.labs.nic.cz/knot/knot-resolver/issues/85#note_50539
