Why do you configure from ground up? Don't you have your home directory in a separate partition? I keep it around and reuse it in case I have to upgrade the whole system. When you install most of your configuration into user space (except things like ssl and third party repos) it becomes easier to recover from a full system upgrade. Worked for me past 10 years.
