Minimum package selection

Hi everybody, I am currently trying to install a secure backup file server with Suse 8.1. As I only want to install the strict MINIMUM among the packages available, I wonder if anyone has done the same before, i.e. selected a minimum set of packages which allows you to boot your box correctly and not much more. To do this I have installed the Suse minimum installation and deselected lots of packages, but I am not sure whether I can still take away some more packages..... "rpm -q -a | sort " gives me the attached list and y wonder if I can reduce further more this list. Any help or comments are greatly appreciated Lars
