You are rebooting your hardware.  You shouldn't try to initiate that 
from chroot.

Yes.  That's what the book says to do.

The only commands left after that are in section 8.4.4 and 9.1.  Section 
9.3 is just cleanup.  If you reboot into the new LFS system at section 
8.4.3, you can do 8.4.4 and 9.1 from there and 9.3 is not necessary 
other than to test what you did in section 8.4.4.
