Drew, good to see you're still around. It has been a long time.

I got no error or anything when I tried. Since I posted, I configured 
and compiled shadow using the book
instructions for its installation in Ch. 6, removed the su I had copied 
earlier, then ran

<install -c -o 0755 src/su /tools/bin>

I got the same results--nothing. I was still root after I ran <su 
linux-headers>

I'm stumped. I don't know where to look to troubleshoot. Rob Taylor just 
installed shadow before the linux headers and su worked. He reinstalled 
shadow in the normal course of things. This causes a few hiccups during 
Ch. 6--largely with install directories. I found an "su" file that is 
installed to /etc/pam.d, but since Ch 6 configures shadow not to depend 
on pam--because it's not installed--I doubt that would have any affect 
on the situation.

Before I give up and install the entire shadow pacakge, I'm probably 
going to do a DESTDIR install somewhere in /mnt/lfs and try coping the 
binary to /tools/bin. We'll see what happens.
