[sllug-members]: Environment/Path help

[weales at xmission.com]

Ok, I've been using *nix for over six years (and I feel like a total 
n00b for asking this question), but I need to know how to "source" my 
root user environment variables ($PATH) after I su.

I ssh into systems as a non-root user and then su.
How can I easily "source" my root environment?

thanks
Ron
