Bug Description

Step to reproduce:
    apt-get -y install maas

This hangs on "initctl emit rabbitmq-server-running". According to a discussion in #ubuntu-devel yesterday, this is the wrong way to do it.

Bug 966269 is related: we need a way that works both when maas is installed from the installer as well as when installed later.

Workaround: run both "sudo initctl emit filesystem" and "sudo initctl emit net-device-up". Both are needed and both will hang. When the original emit is freed, the "emit filesystem" will continue to hang. But at least you'll have maas installed.

  [ Dave Walker ]
  * debian/rabbitmq-script-wrapper: Use start-stop-daemon instead of su
    to run the commands. This also allows rabbitmq to start on the
    installer if invoke-rc.d is used with --force. (LP: #966269)

  [ Andres Rodriguez ]
  * debian/rabbitmq-server.init: Use --no-wait in initctl emit command to
    not stall apt-get installations. (LP: #968124)
