systemd.service(5)

   [...]
   ExecReload=
   [...]
   
   One additional, special environment variable is set: if known,
   $MAINPID is set to the main process of the daemon, and may be
   used for command lines like the following:
   
   /bin/kill -HUP $MAINPID

Am I missing something?

Best
  Donald
