In the past I had implemented "rc{service} rotate" to send SIGHUP to the daemon as "postrotate" action. After converting (actually being converted ;-)) to systemd I dropped the LSB script, and wonder which command to use as "postrotate" action:

that's what reload is all about

[harry@srv-rhsoft:/etc/systemd/system]$ cat named.service | grep Reload
ExecReload=/usr/bin/kill -HUP $MAINPID

[harry@srv-rhsoft:/etc/systemd/system]$ cat rsyslog.service | grep Reload
ExecReload=/usr/bin/kill -HUP $MAINPID
