except for
             HOME, SHELL, PATH, TERM, LOGNAME, and USER.  HOME and 
SHELL are
             modified as above.  LOGNAME and USER are set to the
target login.
             PATH is set to the value specified by the ``path'' entry 
in
             login.conf(5).  TERM is imported from your current 
environment.
             The invoked shell is the target login's, and su will 
change
             directory to the target login's home directory.

Known for decades, sure. Still wonder what changed. Machines are pretty 
extremely default setups.
