I tracked down a RedHat bug report about this very issue which was  
closed as not a defect. [do not have reference handy right now]. It  
was closed for the completely spurious reason that no-one could  
possibly wish to
invoke an an interactives shell from a command launched with su -c.

I shall attempt to do battle with this mind-bendingly closed-minded  
myopia in the appropriate forum. Grrr!
