The solution proposed by vlfig works. But, I think that it can be improved. In my example, I'm trying to run the Puppet agent after cloud-init is finished. In my case, we wanted Puppet to only run after Cloud Init is done with its set up. In order to achieve that, we need to modify the setup of its systemd unit. The default execution order for the ...
