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

[Sebastian Mangelsen]

Hi,

we're running into the same problem and wonder whether we could use a
sub-string of the MAC address instead. Does the UDEV library support
something like $env{MAC_ADDR:6}?

  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.
