Note that these two lines are the implied default, and hence redundant.

Hmm, quite possibly rsync has some logic built-in that checks whether
it is run with PID 1 as parent process, and then changes its logging
behaviour. On sysvinit that made some sense, but it certainly doesn't
on any other init system.

Please check if there's a logic for that in rsync somewhere!
