[slurm-users] Meaning of "defunct" in description of Slurm parameters

[Paul Edmon]

My guess if I had to hazard one is that they wanted to simplify how you 
define who the controller is.  With the previous method you could define 
it in conflicting ways.  This method is less prone to mistakes.

That's at least my read of it.

I wasn't privy to the decision to the discussion about adding the new parameter, so the value isn't enormously clear, except for the option of adding a second backup host (for a total of 3 "ControlMachine" candidates).
