Newer versions of Unbound require the "include:" line in its own stanza

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet:7.13.1
• Ruby:
• Distribution: oracle linux 8
• Module version: 7.0.0

How to reproduce (e.g Puppet code you use)

inside of a yaml:

unbound::custom_server_conf:
  - 'include: "/etc/unbound/conf.d/*.conf"'

What are you seeing

Having an "include:" line in places in the server: stanza with newer versions of unbound (started with unbound-1.16.2-5.el8_9.6 in ol8 appstream, but also happens with the latest 1.20 version i compiled) will error out upon configcheck.

What behaviour did you expect instead

It'd be nice to have a dedicated module command to set the include: directive outside of the server stanza, in its own stanza like the example config for unbound.conf does:

https://github.com/NLnetLabs/unbound/blob/master/doc/example.conf.in

# Use this anywhere in the file to include other text into this file.
#include: "otherfile.conf"

# Use this anywhere in the file to include other text, that explicitly starts a
# clause, into this file. Text after this directive needs to start a clause.
#include-toplevel: "otherfile.conf"

# The server clause sets the main parameters.
server:
	# whitespace is not necessary, but looks cleaner.
