That's what the "/etc/init.d/spamd status" command is meant to check.
The "... status" will only return success if you are running spamd via
openrc. Likewise, as I understand it (but haven't tested), the
"systemctl try-restart spamassassin" command will only work if you are
*using* systemd and the spamassassin service is running. They should be
harmless otherwise.

For example...

  # spamd --daemonize
  # /etc/init.d/spamd status
   * status: stopped
  # echo $?
  3

If on the first line I had done "systemctl start spamassassin.service",
I should get the same result, so the openrc reload commands will be
skipped for systemd users.

I did take your suggestion and check for rc-service though. I shouldn't
count on openrc being in @system forever.
