I am just wondering what is going to happen when by the end of 2014 similar “packstack multi node set-up via standard prepared answer-files” will run on RHEL 7 & CentOS 7 (F19 based systems) servers landscapes. This slides http://oddbit.com/rdo-hangout-multinode-packstack-slides/ would work for almost any sysadmin, even has no any idea what OS is really on top of OpenStack and what Juju is.
