The problem with this obviously is that the attribute is not removed if
res1 has been fenced.

I still wonder what the use case is.

If I have a) resA and resB, b) resB should only run if resA doesn't.

So now resA fails. It'd be restarted elsewhere, negating the need for
resB to run.

What would cause resA to be unable to run anywhere else?
