Stepping back a bit... why does it need to know the device
name - can't it be automatically determined via route?
Erm, no, FCoE does not use IP, it uses Fibre Channel protocols
encapsulated in ethernet packets, this is all handled
by the kernel, all rc.sysinit needs to do is tell the kernel:
"go talk FCoE on that NIC"
OK. Still, device names aren't persistent. Hardware addresses
are a better key, if possible.
Agreed, but in the end we need to echo a eth# name to
a sysfs file

... really?

Really!

What happens when the name changes in the kernel? (I
assume it's actually storing the device index, or similar.)


I have no idea.
