Can cf-agent easily know about "systemd" state/target, etc.?

Context: Linux "systemd" machine; CFE 3.18.

We have an emerging use case to run a specific, minimal (i.e. fast) subset 
of our cf-agent policy during machine shutdown/halt.  We are considering a 
"systemd" service with something like:

    ExecStop=cf-agent....

Is there something already in place which can tell us the current state 
(target?) of systemd?  Perhaps a "var" (e.g. "sys.") in CFE?  Or perhaps 
something in "/proc" or similar that our policy could peek at?

Failing that, we do could something like:

    ExecStop=cf-agent ... -D HALTING

Thanks.
