xinetd reload via systemctl impossible: another systemd shortness or what?

[Frantisek Hanzlik]

"systemctl reload xinetd.service" return message:

Failed to issue method call: Job type reload is not applicable for unit
xinetd.service.

It is on Fedora 16 i386, fully actualised.
Command "kill -HUP XINETD_PID" is working flawlessly.
It is some known systemd problem?
