Hey there, starting a thread in regard to RHEL 8 Beta.
My part: I did initial testing of provisioning, 1.20 out of box has one small issue with ntp package which is no longer available in RHEL8 (at least in the base OS). Luckily Anaconda asks to skip missing package (new feature I guess).
There is a small patch proposed for 1.20.1 which solves this:
Other than that, provisioning part works just fine. There are some visible improvements in Anaconda text mode (downloading progress, more info on the console) which is great.
Please add your own experience with puppet, ansible, other plugins etc!
