Re: 3.18.1: duplicate cf-exexd processes

Hello there

I am hitting a related problem in Debian 11.

I have just ported by policies from 3.15.5 to 3.18.1. I got both 
CFEngine and systemd complaining about the duplicated process so I 
applied Nick's patch, and now I have a different problem.

I have not completely understood what's going on. Is it cf-agent that 
starts a new cf-execd? Or is it cf-execd that clones itself and then 
spawns cf-agent, but then doesn't terminate? Whatever it is, when the 
new agent run starts, one cf-execd is killed (by what?), then the agent 
starts, and then systemd complains again about the duplicated 
cf-execd... I am trying to figure out, but my brain is already in bed 
tonight.

Anyone who knows better about the changes around cf-execd in 3.18 and 
understands what the heck is going on here? And, especially, how to fix 
this?
