Hi,
in the last days I tested the installation a lot and can provide a puppet style install script on [1] and an OpenStack user-data file on [2]. Let me know if you like a proposal in system-config in this way. In the PoC is also a solution to implement a valid ssl cert for the check site.
kind regards
Frank
