Seems to me that it would be a lot cleaner to use upstart's generic way
of emitting events than teaching the specifics of UPS handling to
upstart itself.

That is, make the UPS daemon run something like

    /sbin/initctl emit power-status fail -eTIMELEFT=120
    /sbin/initctl emit power-status ok

and let the /etc/event.d jobs handle the event as they deem fit.

But that's only my opinion.
