Along side Genesis we use additional internal tools that "provision" physical hardware using Kickstart specification.

One of the challenges with provisioning machines is bringing visibility to the process of provisioning while the machine is being provisioned. Kickstart and Anaconda installer aren't ideal from a visibility stand point.
