Summary:	"sudo su -p" does not preserve the environment

Description Greg Steele 2003-04-29 13:40:07 MDT

According to the documentation for su, the "-p" option should preserve the 
environment variables `HOME', `USER', `LOGNAME',or `SHELL'. When executed from 
the login shell, these variables are preserved. When executed using 
sudo, 'HOME' is preserved, but 'USER' and 'LOGNAME' are set to 'root'.

Sudo sets USER and LOGNAME to the target user.  If you don't want this, you can 
use a line like this in sudoers:

Defaults    !set_logname
