[Andreas Hasenack]

artful still has the same /lib/udev/bridge-network-interface script in
its bridge-utils package, fwiw.

Title:
  udev script shortcuts ifup-scripts

Status in bridge-utils package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  I just ran into a problem. I've configured a bridge as a virtual lan
  (for lxc, lxd, and these things), but also configured an USB Ethernet
  dongle to be part of the bridge.

  If the dongle is present at boot time or if the dongle is put in while
  the bridge is down, then

  
  /lib/udev/bridge-network-interface  

  
  tries to take the bridge up. Nice. 

  But it does not call ifup, instead it directly calls

  IFACE=$port /etc/network/if-pre-up.d/vlan

  
  This ifup is not aware that the interface is up and still thinks it would be down, and all the other settings (up/down-scripts ...) are not executed. Breaks functionality (and can be a security problem, since firewall settings my be skipped.)
