Use case:
When configure Red Hat Linux installation via Ansible and Kickstart at the end of installation process there is need to reboot a machine. Without "Rollback this configuration during reboots = True" for Run Once process goes to an installation loop.

[mwperina]

Arik, does it make sense to add that parameter?
