Title:
  ifquery crashing

Status in ifupdown package in Ubuntu:
  New

Bug description:
  Hi,

  I'm just doing some tests where to use an ubuntu machine as a router
  and thus plugging in an USB Ethernet devices as it's second ethernet
  interfaces.

  Unfortunately I can't keep that damned Network manager from renaming
  the device (i.e. from eth0 to  enx0000e80006d8), even if I tell NM to
  ignore the device. Since this happens before udev, it confuses several
  udev scripts).

  In context of this problem I found lots of messages in /var/log/syslog
  of the kind
