For some reason I can't remove system-config-network from my system. yumex tells me that there is a dependency on 'system-config-keyboard' (as well as on the package 'firstboot'). I'm fairly sure that I don't want to remove system-config-keyboard, and I couldn't see any reason why the latter should be a dependency of the former. I figured that having installed NetworkManager on my system, system-config-network would now be redundant, right?
system-config-network is needed by firstboot... and no, NetworkManager does not fully replace s-c-network
