you would use the

service

task from a puppet run? I thought about it being weird managing itself, but I just tested this and the systemd unit has

KillMode=process

, so restarting the service doesn't kill the puppet process that is applying the catalog, so it seems to achieve the desired effect of instantiating a new environment for the agent

Hmm. That seems like a potential problem. There are loads of situations where you want a restart of the service to clear out old runs that may be hung.
