Thank you for your detailed reply.
Yes, I use the new version of s6-boot.
If the system runs smoothly, I'd prefer to have no any logs at all (or maybe, optionally to send them all to >/dev/null). But in case logs are needed, it would be an option to turn them on.
Also, logs grow with time. Maybe, it's possible to zero log size automatically?
And how do you handle your logs?
do you mean deleting all e.g /var/log/s6serv/daemon/current file for all daemon?
If yes, what would happen?
