CentOS - Jan 2016 - systemd: SIGPWR handler for Centos 7.2?

Hi folks,

it seems that sigpwr.target is just a dummy. Something
like
	kill -PWR 1
or
	systemctl isolate sigpwr.target

is visible in the journal, but it does not power down the
host.

This breaks a clean shutdown of LXContainers setup with
Centos 7.2. I would guess there are problems with UPS
monitors, too.


Is there a workaround? Every helpful comment is highly
appreciated
