Subject: [PATCH] system/puppet: add --certname parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

certname [1] can be a useful parameter when we need to specify a
certificate name different from the default value [2] in Puppet.

Ex: the hosts have different names, in advanced network isolation
setups.

Also, it can be used when we want to run Puppet with a specific node
definition and not using hostname or fqdn to match the nodes where we want to
run Puppet [3] (not recommended by Puppetlabs though).

[1] https://docs.puppetlabs.com/puppet/latest/reference/configuration.html#certname
[2] Defaults to the node’s fully qualified domain name
[3] http://docs.puppetlabs.com/puppet/latest/reference/lang_node_definitions.html#naming
