Yes, I have read both of those pages, but I thought they confirmed my
impression that sudo gave restriction on privileges whereas su did not.
Thanks for correcting my mis-impression.

But the converse is true if that is the case: sudo gives no greater
protection than su, so why make it the default for Ubuntu?  Why not
continue using the default Debian used?
