Correct, my short term memory isn't that error free any more.

They used to, and that has always been the first place I check when the 
net doesn't come up. What I am not sure about is which version it got 
changed in. Its been a while though, as I note the one wheezy install I 
still have running on another copy of that same hardware, is using eth0 
but its not in the /dev/net tree either. So I'm the one out of date it 

The whole point is that the most recent V 2.8 LinuxCNC install hasn't 
pinned the kernel, and that it didn't work again until I had rebooted 
to -rt11 from the newer -rt13, and its now works correctly for all 
versions tried, but didn't at 8:15 local time this morning.

There should be a reason, but I've not found it.
