Here's how I do it. Install a box via kickstart that does not have
anything in 
%packages
boot it.

install yum-utils - specifically for the package-cleanup script

run:
package-cleanup --leaves --all


that's a list of all the packages upon which nothing else depends.
- sift that list and remove all the stuff you don't think you need
- run it again
- sift it again
- run it again
- sift it again

yum list installed

see how many pkgs are there and make sure there's nothing in there (that
something else may depend on) that you know you don't need.


This is what Jesse Keating got Fedora7/Rawhide down to:
