Title:
  transient error results in /etc/resolv.conf not populated in iscsi
  root

Status in open-iscsi package in Ubuntu:
  Confirmed

Bug description:
  similar to the issue described in bug 1463461, i am now seeing
  transient errors resulting in /etc/resolv.conf not having any
  nameserver entries when it should.

  The reproduce is similar
   http://bazaar.launchpad.net/~smoser/maas/maas-ephemeral-sniff/view/head:/README.txt

  ./get-maas-eph wily.d wily

  # you probably have to fix 'ipaddr=' in ./tgt-boot-test
  # or set HOST_IP= to some ip address valid for your host.

  ./tgt-boot-test wily.d/root-image wily.d/hwe-w/boot-kernel
  wily.d/hwe-w/boot-initrd

  login with 'ubuntu:passw0rd'
  and cat /etc/resolv.conf.
  you should have something there.
