The service module made some assumptions about how a service should be managed based on what was installed on the system in terms of service

management tools, which meant upstart services on CentOS6 were not startable.  This tweak allows things like vmware-tools to be controlled
via the service module.  More testing on other distributions (particularly with systemd) is presumably needed.
