no the problem was that it appended a new device at the end of the old
file. the old file applied to the previous motherboard (I kept the
same disk). so then when I brought up the new motherboard it
apparently kept the old devices and tacked the new eth onto the end, so
eth0 ended up being renamed eth3.
I see why though. a device might come and go and you want it to keep
the same name. so udev can't assume the devices are "gone", they might
just be "resting". beatiful plumage, the norwegian blue.
