 # munin::master - Define a munin master
 #
 # The munin master will install munin, and collect all exported munin
 # node definitions as files into /etc/munin/munin-conf.d/.
 #
 # Parameters:
 #
 # - node_definitions: A hash of node definitions used by
 #   create_resources to make static node definitions.
 #
 # - graph_strategy: 'cgi' (default) or 'cron'
 #   Controls if munin-graph graphs all services ('cron') or if graphing is done
 #   by munin-cgi-graph (which must configured seperatly)
 #
 # - html_strategy: 'cgi' (default) or 'cron'
 #   Controls if munin-html will recreate all html pages every run interval
 #   ('cron') or if html pages are generated by munin-cgi-graph (which must
 #   configured seperatly)
 #
 # - config_root: the root directory of the munin master configuration.
 #   Default: /etc/munin on most platforms.
 #
 # - collect_nodes: 'enabled' or 'disabled' default 'enabled'.
 #   Makes puppetmaster collect exported node_definitions.
 #
 # - dbdir: Path to the munin dbdir, where munin stores everything
 #
 # - htmldir: Path to where munin will generate HTML documents and
 #   graphs, used if graph_strategy is cron.
 #
 # - rundir: Path to directory munin uses for pid and lock files.
 #
 # - tls: 'enabled' or 'disabled' (default). Controls the use of TLS
 #   globally for master to node communications.
 #
 # - tls_certificate: Path to a file containing a TLS certificate. No
 #   default. Required if tls is enabled.
 #
 # - tls_private_key: Path to a file containing a TLS key. No default.
 #   Required if tls is enabled.
 #
 # - tls_verify_certificate: 'yes' (default) or 'no'.
+#
+# - extra_config: Extra lines of config to put in munin.conf.
