I wouldn't wish Puppet to play guess the quantum cat but, rather, to have
the agent's application of its catalog error in a predictable fashion. I'd
like to express the pre-condition that if /etc/apt/apt.conf.d/01proxy exists
in the filesystem then the installation of package apt-cacher should error.
Puppet, I believe, does not have this capability, and so the catalog build
fails in an obscure manner. Do you suggest that it be a poor idea to include
such pre-conditions in the language?
