[Bug 1567744] Re: USB NICs get too long name for ifupdown aliases

[Andreas Hasenack]

I just hit this deploying a MAAS2 xenial node that has a usb nic:

# ifup br-enx0023552c6029

Waiting for br-enx0023552c6029 to get ready (MAXWAIT is 76 seconds).

Failed to bring up br-enx0023552c6029.


It went far enough to create the bridge, but with a truncated name and no IP:
# brctl show
(...)
br-enx0023552c6		8000.0023552c6029	no		enx0023552c6029

  I have a USB NIC that is connected to my denial system. I tried to
  create an alias, and after reboot, it wasn't created. When I manually
  try to bring it up I have the error.
