I've tested four different ways to provide su before starting to build 
the linux headers in Ch. 6.

1. compile shadow and cp su to /tools/bin in Ch. 5
2. install shadow at the end of Ch. 5 as lfs and not root.
3. compile shadow as root in the chroot environment and copy su to 
4. install shadow as root before building the headers in Ch. 6

The only one that worked for me is the last one. The only thing I didn't 
do was configure shadow after installation, and su still worked. I'll 
configure it when shadow is installed in the course of going through Ch. 
6. So, I think this process needs to be added to the hint.

One of the reasons I like Package Users is that it's really easy to 
completely remove the files installed by a package. Installing shadow as 
root this way eliminates that and I don't know that shadow will over 
write it's files when installing as a package user when originally it 
was installed as root. That's something I'll be watching for as I make 
my way through.

This might be the time to mention a trick I learned with find. Using 
"-newer" and "! -newer" in a find command can bracket those files 
installed by one package. You can create a time window that's only two 
minutes wide. I haven't tested the seconds.

Thanks to all who responded in this thread.
