I don't backup system files, just my home directory and `/opt`. I do often end up with some installed packages used only for testing/troubleshooting. The ~/System directory allows me to rebuild a system after a disaster or configure a new machine to my needs. It is not hard to determine which packages are missing in a fresh install. A list of installed packages right after a fresh install could be used to generate a list of stuff added after the initial install, but if you end up doing a fresh install on different hardware you might see some different packages (graphics and network). -- George N.
