One issue that occurred when going from FC-5 to FC-6 on my desktop was that the order of the 3 ethernet devices changed. This didn't really cause a problem; I simply permuted the files /etc/sysconfig/network-scripts/ifcfg-eth[012]. But I wondered: 1. What caused this change? 2. Is there any simple way of ensuring that a given device is say eth0?
You can use the HWADDR parameter in each ifcfg-eth[012] file to specify the MAC address of the corresponding NIC. This keeps things stable during normal operations. If the cards are all the same, this situation can be a real bear during installation. I guess that's a benefit to going gigabit for my internal network. I left my "external card" as a 10/100 since that's plenty fast enough to deal with the data rate from my ISP.

Cheers,
Dave
