Comment 3 for bug 1578658

So this is a regression from the moving of the puppet sync task from nailgun to library in combination with task based deployment. The ordering is no longer ensured correctly. I've been able to reproduce this issue more clearly by creating a plugin to be deployed prior to controllers (with min controller = 0). You can see Bug 1580295 for more details but this should be a high bug because deployments can completely fail in specific cases due to the ordering of the hiera tasks not properly being defined.
