Hmm, it seems that the build system doesn't fault attempts to do an 
UNPRIVED build into /, at least, it still continues to pass the options to 
install to update the METALOG file.

Does install still attempt to correctly set the install flags in this 
case, or should the Makefiles be altered to fault this case?

Is there any way to force a privileged re-install into / after an unprived 
build?  UNPRIVED is only tested for being defined, not for its value, so 
it isn't possible to override the setting through the nbmake-wrapper prog.
