Pierre, this is really, really helpful. Thanks.
As soon as I can get all my computer things ironed out, I’ll be able to finish the hint. It’s original goal was to do what you have done in a basic LFS system either rebuilding grub before Ch. 8 or waiting until just before Ch.8 to build it. There are a about five packages that need to be built and installed at that time, but it’s doable.
May I include what you have done in the hint for those that use virtualization?
Many thanks again.
