Don't top post.
Also, a post in the thread "LFSv7.4 stuck at section 6.9.1" gave me an
idea about why you were unable to run `chroot /mnt/lfs/tools'. The bash
that lives there requests the dynamic interpreter (run-time
linker) /tools/lib/ld-<whatever>.so and that did not exist.
You can verify this by adding a symbolic link `tools' to /mnt/lfs/tools
which points to `..'. Like this (command run from /mnt/lfs/tools):
ln -sv .. tools
With this, you should be able to do `chroot /mnt/lfs/tools' without any
problems. Just don't execute Section 6. with that setup because you
will have A LOT of problems and a lot of thrashing. ([thinking]...or
maybe not... anyway, don't do it. not when you are building LFS for the
You don't need an AI for a robot uprising.
Humans will do just fine.
