Not really... remember, 'su' simply changes the current user, it doesn't
change the environment. Look at the output of 'env', and you'll see that
things like $USER still have values for the user that ran 'su', not the
user they're becoming. As far as I can tell, $HOME is the only thing
that changes.
That's the difference between 'su' and 'su -' - the latter runs a new
login shell as the user in question, so the environment gets reset,
running the login scripts for root which add the sbin directories to
$PATH.
Simon.
Strange, typing "su" has always added /sbin and /usr/sbin to the path
(while removing "extra" stuff like /usr/X11R6/bin), both on SuSE and
every lfs system I've built. I am aware of what you said, at least in
theory, but I guess I still don't really understand...
