If you choose a net install, it does not. I don't have gnome on my system because personally I don't like it,
but I have KDE (3.3.2) Fluxbox (love it !!) and Xfce4 (love it much, too). Just get rid of one of the 2 if you
don't like either one or the other...
Netinstall : use "aptitude" : a really useful tool : you can choose any packages you want to d/load / install
