One of the things about being a Consultant in Red Hat or any other consulting company, is that sometimes cannot control how SO installations are performed. Sometimes all you get is a “naked” SO installation with default options selected and you need to work your way up from there. You can do automated installations using Kickstarts but needs a VM or server with no SO whatsoever.
What’s the problem with this? Not much if you are just installing one or two systems at a time. However, what happens when you need to do the same installation on more than 4 servers? Say 10? You get the idea.
