Depending if you do a "su" or "su -" you will get different results.
The latter effectively performs the same stuff a "login root" would
do.  The "su" only changes some minor things.

Homework:
	% pwd
	/foo/bar
	% su
	% id
	uid=<non-zero> gid=<something>
	% pwd
	/foo/bar
	% ^D

	% pwd
	/foo/bar
	% su -
	# pwd
	/
	# id
	uid=0(root) gid=<something>
	# ^D
	% pwd
	/foo/bar

I tend to use "su" only when I need to read certain files.  I use "su
-" for more major work.
