Yeah, so there's userspace tool, and currently systems _with_ that
tool work poorly with UPS.

So you have fixed that, and now, systems _without_ that tool will work
poorly.

That's not a fix for serious bug, that's behaviour change. You are
fixing one set of systems and breaking another.

I don't believe it is suitable for stable.
