I'm in the process of moving our servers from RHSM to Satellite, and the question arose, "How much testing do you need to be sure it's working?" By working, what was meant was "Getting software updates".
I have a variety of answers for that. One is that once I've seen a machine correctly communicate with Satellite and do something--an update, an install, whatever--I've seen it work. Another is that seeing an update, an install, and an erase shows me a variety of functions are working. Another is that until you turn on automatic updates, you don't know that it's really doing what it should.
What do you folks do?
