So you are saying that logrotate *already* does a HUP but
the problem is that it is "HUP-ing" based on /var/run/syslogd.pid???

Is this a new way to not only avoid modifying logrotate
but also avoid -p switch!?!?!?!?!.....

I can just make a soft link from /var/run/syslogd.pid
to /var/run/syslogd-ng.pid!!!

This is an even neater solution.
