Boiling Down Slackware Linux to the Essentials?

noxious420 asks: "I need to crank out a large number of very basic Slackware based Linux boxes. I am familiar with the "canned" distribution sets that FreeBSD uses and I want to use a set similar to the "Minimal" - "The smallest configuration possible" set. In Slackware's Expert install mode, I have been able to boil it down to the very bare essentials that it needs to run, but there are some unused and leftover directories that I had to manually delete. I don't want to clean up these directories every time. Is there some way to get a true "minimal" Slackware install? "
