docker crashes if journald is restarted

• Ansible version (ansible --version): 1.9.4
• Python version (python --version): 2.7.6
• Git commit hash or branch: master
• Cloud Environment: n/a
• Terraform version (terraform version): v0.6.11

Our docker install is affected by the bug described in https://bugzilla.redhat.com/show_bug.cgi?id=1300076. If the systemd-journal service is restarted, docker will crash.

Presumably, this would not occur if Docker were built on go 1.6.

Newer Redhat packages include the docker-forward-journald package to work around this problem

Still reproducible:

[centos@mantl-control-03 ~]$ sudo systemctl stop systemd-journald
Warning: Stopping systemd-journald.service, but it can still be activated by:
  systemd-journald.socket
[centos@mantl-control-03 ~]$ sudo systemctl stop systemd-journald.socket
[centos@mantl-control-03 ~]$ sudo docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
