The original workaround was for an init script that grabbed stdout.
This was some time ago and I think it's safe to remove.
It can be a problem on Fedora; out-of-the-box some old F20 images can
have a broken dependency when rabbitmq installs. With this in place,
all helpful output goes into the temp log file, but it is never shown
because the install_packages function exits the script. Thus things
just stop and you have no idea why.
