The rotator should send the -USR1 signal to the master process.
The master process reopens files, does chown() and chmod() to enable
the worker processes to write to files, and send a notification to
the worker procesess. They reopen files instantly.
If the rotator sends the -HUP signal, then them master does a reconfiguration
and starts a new worker processes those write to the new log files, but
the old shuting down worker processes still uses the old log files.
Any way, to send the -USR1 signal you should have the sudo permission.
