Let's say you start from the base system, then install a couple dozen command-line utilities from cowsay to whois, then you install the "X Window System" group, a couple dozen fonts, then the WindowMaker window manager, then a handful of X applications... how do you manage from there to get back to exactly the base system you had from the start? I know this may sound a little academic, but it's for a little private experiment here.
