Description of problem:
Make it possible to persist facts/reports when host is being rebuilt

Version-Release number of selected component (if applicable):
Red Hat Satellite version 6.1.3

Issue :

For customer 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.

Actual results:
All reports and facts are cleared.

Expected results:
Make it possible to persist facts/reports when host is being rebuilt
