It does not go down, because the dependency is the other way around. The 
service requires its log service, but the log service doesn't require 
its service to start (it's just useless without it).

s6-rc -u change foo starts a service and all its dependencies (including 
its log service). s6-rc -d change bar stops all services depending on a 
service and the service. Stopping the log service stops the service as 
well. Starting the service starts the log service.

Oneshot services are started by the s6 oneshot runner. This long running 
service is required to start oneshots in a clean environment.

What problem are you trying to solve? s6-log shouldn't have deal with 
replacing an other s6-log process itself.
