Public bug reported:

When starting a Vivid container, it fails to get an IP address.  It
believes networking.service was successful, but actually it dies with
SIGPIPE.  Restarting networking.service gets an IP, as expected.

Starting networking used to work with pre-vivid containers.  I'm
reasonably sure this fails 100% of the time.  Limited user container,
very standard setup (no unnecessary config; cgmanager and lxcfs
installed), btrfs filesystem but not btrfs-backed (as it's limited
user), ...
