Boohoo!!
 

Srewed the pooch, I'm starting over from a fresh format.
I did something wrong in the beginning of ch#6 I think when I changed ownership I diden't have some thing set right because when I tried to log on after a reboot . My desktop managers were saying I diden't have the right permissions I did get logged on as root under failsafe but everybody still disowned me

Got another ? when I set the $LFS variable do I need to reset if I reboot or logon?

Ouch. I know exactly what feels like.

I did the exact same thing a few days ago. In my case I forgot to chroot to /mnt/lfs before running the chown 0.0 command. It took me a few days to fix everything up again ownership wise.

In your case, yes $LFS is unset as soon as you exit your shell, unless you put it in your $HOME/.bash_profile or $HOME/.bashrc file. With $LFS unset, you chrooted into your host distribution (ie; the same effect as simply starting another shell session).
