Yeah, it is ambiguous to a degree, but I figure that something named 
/local is actually going to be physically local.  It helps tremendously 
when a user calls up with a problem, say that they can't see a file they 
placed in /local/... on all nodes.  Usually they get quiet for a moment 
after saying that aloud, and then say "oh, never mind".  :)

We used to do this, but things kept getting overwritten by zealous 
package management tools.  So we started using modules and showing 
people how to add paths by hand if they were adamant about not using 
modules ...
