Bug Description

setup_kmsg is a convenience to have container syslog messages (generated by userspace) directed at the console. However it fails the container must not fail to start.

========================
SRU Justification
Impact: certain containers will fail to start
Development fix: if /dev/kmsg could not be set up, don't fail container startup
Stable fix: same as development fix
Test case:
 sudo lxc-create -t sshd -n ssh1
 sudo lxc-start -n ssh1
Regression potential: containers can run fine without setup_kmsg() having run, so allowing container startup to proceed when setup_kmsg() fails should introduce no regression.
========================

To be clear this was fixed in raring with:

lxc (0.8.0~rc1-4ubuntu45) raring; urgency=low

  [ Stéphane Graber ]
  * Allow the container to mount efivars on /sys/firmware/efi/efivars.
    efivars is automatically mounted by mountall on UEFI systems, failure to
    do so leads to a complete boot failured.
  * Allow mounts and pivot_roots under /usr/lib/lxc/root/ for compatibility
    with nested precise lxc hosts (quantal -> precise -> containers).

  [ Serge Hallyn ]
  * update 0227-ubuntu-cloud-parsing to catch a doc typo stgraber had found
    in the upstream review.
  * 0228-ignore-kmsg-setup-failure: ignore failure to set up kmsg, since that
    is not critical.

  [ Christian Kampka ]
  * Have upstart run lxc instances (LP: #1049908)
