This is a RFE to provide a mechanism, to quickly see if a system conforms to specification or not. Make sure RPMs & config files are as expected or not. For RPM you could build release rpms that hold the certified software including versions as requirements. That way you'll see quickly if the systems complies or not. This would also help to prevent unwanted software changes on this system. The config file compliance could probably been checked when puppet gets integrated. In larger customer environments this is a vital feature to keep the environment manageable over time. With this i can easily determine my one-offs. And fix them.
