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'.

Comment 1 Todd C. Miller 2004-01-17 20:38:43 MST

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
