Bashful Configuration Management

In the Server Configuration 101 chapter, we started to write reusable Bash scripts. Because our ambition is a little higher than that, we'll improve on what we did and build a tiny configuration management system. We'll make a reusable collection of functions that will help us to set up virtual servers in a more practical way. What we'll learn in this chapter is the heart of all the scripted demonstrations that come with this book, but you might find it helpful for your little deployment experiments too.
