[colug-432] Psudo Sudo Su

[Steve VanSlyck]

Oh, gosh that was Sunday when I was doing the install. IIRC is was 
something along the lines of command not understood. Again IF I recall 
correctly. My first impression was to check the path statement, but I'm 
pretty new and dinna know how ta' do that Keptin, or what to look for if 
I did. Linus is on the 2d hard drive on this box, so I'll have to shut 
down and reboot. Anything else I should maybe look for at the same time?
