Overview
In GCP some node types don't come with cloud-init so the only thing you can do to automate Puppet startup is to use a startup script https://cloud.google.com/compute/docs/instances/startup-scripts/linux. This startup script runs prior to the full system initialization, thus multi-user target has not been reached.
In our startup script we install the Puppet repo, the puppet-agent package, and then connect to our puppet server for the remaining setup. We're finding that Puppet is hanging for an hour during the initial puppet run, apparently attempting to manage multi-user.target (likely from the changes by @jcpunk in #270)

Now I can guess where you are going, and yes we do set systemd::default_target: multi-user.target and yes I'll remove that. My question is more about whether Puppet should be in charge of making the system move to this target? It doesn't seem likely to be something that Puppet can or should complete on its own. I would think that Puppet should define the target, but not be in charge of trying to take the entire system to that target 😕
In particular, I think that this line is the problem https://github.com/voxpupuli/puppet-systemd/blob/master/manifests/init.pp#L332 and we should consider removing it? I find it hard to imagine a negative impact from the removal, as systemd will ensure that the node reaches the default target will it not? Even if we do need to prompt systemd, I don't think using the service mechanism to try and start this state within the puppet convergence is the appropriate action
