In the attachment you will find the file "/etc/network/interfaces" and
the directory "/run/resolvconf" before ("run-resolvconf-before.tgz") and
after ("run-resolvconf-after.tgz") doing the "sudo ifup br0 br1".

Title:
  /etc/network/interfaces: "dns-nameservers" entries for bridge "br*"
  interfaces are ignored i.e. they are not listed in "/etc/resolv.conf"
  when invoking "ifup" command

Status in “resolvconf” package in Ubuntu:
  Incomplete

Bug description:

  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  apt-cache policy resolvconf

  DESCRIPTION:
  network-manager: My "eth0" and "wlan0" cards are managed by the network-manager and this works fine.

  /etc/network/interfaces: My 2 bridges "br0" and "br1" are managed in "/etc/network/interfaces" as follows:
  ...
  iface br0 inet static
   address 192.168.10.1
   netmask 255.255.255.0
   dns-nameservers 192.168.10.2
   bridge_ports none
   bridge_stp off
   bridge_fd 0
   bridge_maxwait 0

  iface br1 inet static
   address 192.168.0.1
   netmask 255.255.255.0
   dns-nameservers 192.168.0.2
   bridge_ports none
   bridge_stp off
   bridge_fd 0
   bridge_maxwait 0
  ...

  When I now bring up the bridge interfaces using:
  sudo ifup br0 br1
  Then they show up fine in "ifconfig".
  BUT "dns-nameservers 192.168.10.2" and "dns-nameservers 192.168.0.2" DO NOT show up in "/etc/resolv.conf"

  WORKAROUND: Until this has been fixed the following workaround works fine for me:
  sudo vi /etc/resolvconf/interface-order
  #Add the following entry (this entry can be put on any line BUT it has to come before the last entry "*"):
  ...
  br*
  ...
  *

  PS: Based on the workaround in "/etc/resolvconf/interface-order" I
  think the issue is in package "resolvconf" otherwise I would have
  reported the error against the "ifupdown scripts".
