True. I cannot generalise like that. I was only thinking about RHEL and IDM(RH version of FreeIPA) - those documentation as super thorough and very helpful IMO.

Openshift is something Redhat is pushing heavily, and the documentation is extremely good. Also, several of the openshift devs frequently comment here on HN.
