Can you give realistic examples for these? Can you explain what you
are intend to run as PID 1 in them instead? What is cleaning up /tmp
for those things? What is setting up the tmpfiles bits in /run for
them, and so on?
The recommendation for docker containers is to only have one process, when it dies, the whole container stops, this is how to manage a cluster and know when something die.
