I do the same, but my question is: how to do that the other way around? 
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.
