Hi there,

I'm having some issues configuring dnstap.  I'm using Knot version 2.5.1, installed via the `knot` package on Debian 3.16.43-2.  As per this documentation, I've added the following lines to my config file:

mod-dnstap:
  - id: capture_all
    sink: "/etc/knot/capture"

template:
  - id: default
    global-module: mod-dnstap/capture_all

But when starting knot (e.g. by `sudo knotc conf-begin`), I get the message:

error: config, file 'etc/knot/knot.conf', line 20, item 'mod-dnstap', value '' (invalid item)

error: failed to load configuration file '/etc/knot/knot.conf' (invalid item)

I also have the same setup on an Ubuntu 16.04.1 running Knot version 2.4.0-dev, and it works fine.

Any idea what might be causing the issue here?  Did the syntax for mod-dnstap change or something?  Should I have installed from source?  I do remember there being some special option you needed to compile a dependency with to use dnstap when I did this the first time, but I couldn't find documentation for it when I looked for it.

Thanks!
