downgrade from "workstation" to "server"?

[sparkies]

hi,
i'm trying to find out how to downgrade from the "workstation" setup type, i.e. with all graphical options, bluetooth, cd burning, gnome, x11 etc installed, to a "server" setup type, so just the basic stuff required for webserving... without having to identify by hand each package? i cant reinstall from scratch. this is with fedora core 6.
thanks,
andres

Use "yum groupremove" to get rid of package groups you don't want.
