If you understand the technical points of the above, then the above
isn't necessarily true.  I like to have a staticly compiled version of
bash available in /sbin, since the sh that ships is horrible to use.  If
you don't understand what I just said, and can't figure out how to do
that, then please don't try, and you're liable to foul something up.  :)
