Another broken config tool in FC4

[Amadeus W. M.]

After my ordeal with the network (I wasn't getting a default gateway
because the network files were not being written out properly by
system-config-network when choosing dhcp), I found another config tool
that doesn't do what it's supposed to: system-config-securitylevel.
I was trying to get nfs working, and though I had nfs and portmap ports
open, I figured from rpcinfo -p that I also needed the mountd ports open.
So I tried to add them in system-config-securitylevel, but iptables
remained unchanged. Had to insert the rules manually, iptables-save, etc.

I'm surprised I don't see other people discovering non-working
configuration tools. Is there something wrong with my gnome installation? 
Or does everybody else configure stuff at the prompt? 

At any rate, maybe gnome10 was not ready for prime time.
