I tend to agree.
What I'm working on at the moment is correctly marking dependant
actions as unrunnable and providing some reasonable feedback to users
when the situation occurs.

So from (one of) your examples, pe-input-3.bz2 now emits:

 warning: stage8: 	Cannot shut down node 'bl460g6a' because of
dummy02: unmanaged, failed
 warning: stage8: 	Cannot shut down node 'bl460g6a' because of dummy01: blocked

Does that help?

I also need to correctly distinguish between your case and "i want
pacemaker to exit and leave the services running".
