Puppet e MCollective
Um puppet.dll foi adicionado a /usr/libexec/mcollective/mcollective/agent e reconhecido pela MCollective assim que os serviços foram reiniciados.
[vagrant@localhost ~]$ mco plugin doc
Please specify a plugin. Available plugins are:
Agents:
puppet Run Puppet agent, get its status, and enable/disable it

Problema
Embora um host seja reconhecido, não é possível executar o Puppet em um host usando o MCollective.
[vagrant@localhost ~]$ mco rpc puppet runonce
Discovering hosts using the mc method for 2 second(s) .... 0

Tentando resolver o problema lendo este guia no momento.
Parece que o plugin Puppet não é reconhecido pelo cliente.
