This is true, sadly -- but the documentation exists and community is friendly to those who wanna build those skills. It's extremely difficult to build something the size of OpenStack without making it so configurable that operating it needs a decoder ring. I'm doing everything I can in Ironic to make it more friendly and flexible out of the box, but it's a difficult problem to solve.

I always tell people: OpenStack can do almost anything you want... if you can configure it to do so :).
