On my Ubuntu laptop, just su'ing, no dash, works as you describe. Send the
output of env after you su. On Debian 3.0, su'ing without the dash also
works as you describe.
I can't get 4.0 installed because it doesn't recognize my ps2 keyboard. So
I can't test the behavior of 4.0. Perhaps there is some new secuity dealie
that changes the default behavior. I downloaded the latest testing CD last
night, If it works I'll let you know how it su's.
