Comment 12 for bug 570828

BTW, I'd like to emphasize that network-manager is not a good solution for assigning static IP address. Sometimes due to some reason, the network link is down a few secs ONLY, then network-manager will make the service, e,g, dhcpd not working. A dhcpd service restart is required to make work again. This is really annoying especially when the machine is some kind of server. This is why the function to configure network settings in gnome-network-admin is very crucial.
My 2 cents.
