Searched before composing these questions. Working in Void I want to see a log to understand why a daemon isn't working. Therefore according to https://docs.voidlinux.org/config/services/logging.html installed socklog-void and enabled socklog-unix and nanoklogd. "Enabled" within the limits of my understanding.
Susequently found https://smarden.org/runit/dependencies stating "write all logs through runit's logging facility. ... Therefore there's no need to depend on a system logging service." nanoklogd and svlogtail aren't needed to monitor a daemon? Clarification welcome, thanks, ...
