unbound init: erroneous default for control-key-file
There seems to be a copy 'n' paste error in the unbound init script in line 208:
set_quoted_parameter control_key_file control-key-file "/etc/unbound/unbound_control.pem" set_quoted_parameter control_cert_file control-cert-file "/etc/unbound/unbound_control.pem"
The control-key-file variable should be set to: "/etc/unbound/unbound_control.key"
