LOL, maybe "assuming the right code" can be the new "fairly doable" ;-)  `chef-rewind` allows the `start_command` to be specified directly within the rewind block, by using `#instance_exec`, so it's effectively the same approach.

You are correct, this is a different approach to what @jsuchome did before.  It's still a bit ugly having two (Chef) resources effectively able to manipulate the same (Pacemaker) resource, but if it works, it's probably OK ;-)
