I reset root's password and then realized I, when I tried to run su, may 
have been misleading in this post. The actual return I get is:

Crypt: Invalid argument

I don't know if this changes any of the pointers or any of the 
troubleshooting suggestions, but I haven't done anything with 
configuring sudo yet. Since, Bruce indicated that "sudo should not 
affect su," which is my experience too, albeit in other distros and not 
LFS, I wanted to try to develop the ability to use su without messing 
with sudo--if I can.

I also, as I read my original post, realized that I may have been 
misleading in the overall picture. Sudo works great, and I have not run 
into any problems with it
