Comment 3 for bug 964882

In any case, leaving the system unconfigured (even if it is a container) properly may be seen as a bad thing. In case of this bug we can assume the administrator has specified net.ipv6.conf.{all,default}.autoconf=0 prior to starting the container thus disabling autoconfiguration everywhere so ifupdown failing is a bad thing.

I will add the ifupdown project to the task.
