Thanks for the input, Jeremy. Though I still don't understand how
this relates to my question.

My question is about the finished binaries. In the example you give
above, it doesn't have anything to do with the finished product. It
only has to do with failures *getting* to the final product.

I realize that the process as Jim outlined eliminates problem hosts.
But what about for hosts that can build without issues?

The need to reboot and build from the console is an overwhelmingly
big new difference. To the point that I would have to find a different
build method than what Jim described.

I have build scripts, but I don't run them. I cut and paste them. I
wish to examine the output of each command before continuing the build.

Especially with new versions of LFS. Sure it takes me a bit longer
to do it this way, but everything is checked out as I go along. I
don't have to go back and figure out what caused something to fail
along the way because of a problem 6 packages ago.

I'm just asking questions because it seems to be a huge new difference
in the build method. Nothing of which benefits me. Sure this sounds
as if I'm disappointed that LFS doesn't cater to my needs, but our
current build method works well, for the large majority of readers.

Shouldn't we continue to cater to the large majority. I liked Jeremy H's
idea about a split in the book when it comes time to reboot or chroot.

Shouldn't we investigate to see if something like this is feasible.
That's all I'm asking.
