A software generates an kind of UUID when being installed. This UUID is used to connect to a third system which keeps track of the systems reporting in by the UUID and not by a hostname/DNS-name. The UUID can be gathered via a custom fact via puppet and also can be written by a given puppet module if the fact is available.

Upon rebuilding a host, all reports and facts are being cleared, thus making it impossible to access a fact in order to rebuild the UUID in the conffile.

Generally I'd like to be asked whether all facts/reports should be deleted when re-building a host. Ideally I can select if only reports and/or reports should be deleted.
