Thank You so much.  That works here too.  I wonder if= this deserves a=20

It's NOT intuitively obvious that:=20

I don't see how 'a' is possible. All rc.conf does is defne a bunch = of environmental variables. I don't see any way the order is relevant other= than that a later definition of a variable overriding an earlier one. What= am I missing here?=20
