If there are no lines between sets of actions, then Pacemaker thinks
they're unrelated (from an ordering perspective).
Arrows indicate a (first) --> (then) relationship.

Ones with orange text are place-holders
Ones with black text are real actions
Ones with green borders are actions we'll try to execute
Ones with dashed red borders are actions we'd like to execute but
can't (for some reason)
Anything with an arrow pointing to it from dashed-red action will
never be run.


Apologies for not replying to your other problem also, I'm simply
swamped at the moment.
