As I observe students building LFS, I see them make a lot of mistakes.
This is not necessarily bad as making and correcting errors is a good
part of the learning process.
What I would like to do though is to provide sanity checks during
Chapters 5 and 6 to try to catch mistakes earlier in the build process.
I've seen students progress well into Chapter 6 when they've made some
errors in Chapter 5 and they then need to go back and restart Chapter 5.
One problem that seems to pop up a lot is students running make and then
forgetting make install.
What I have thought about is to produce a simple list of files of
critical directories at appropriate times where a comparison to a
reference list could highlight missing files.
Appropriate check points that I've thought about is at the end of
gcc-pass2 in Chapter 5 and after gcc in Chapter 6. Two other logical
locations would be at the end of each chapter.
What I tried in Chapter 5 after gcc-pass2 was
ls -RF /mnt/lfs/tools/{bin,sbin,lib} > /tools/chap-5.10.files
and a similar command at the end of Chapter 5.
This wasn't really satisfactory, It produced files of 1688 and 4979
lines each and the format was not the best when looking at the contents.
A lot of the files are headers buried deep into /tools by gcc and the
kernel.
One thought I has was to do
find /mnt/lfs/tools/{bin,sbin,lib} -maxdepth 1|sort
which at the end of Chapter 5 is 607 lines.
For Chapter 6, I think the following might be reasonable from inside
chroot:
find /{bin,sbin,lib} /usr/{bin,sbin,lib,libexec} -maxdepth 1|sort
which provides a file of 1055 lines.
So, what do you think? For a sanity (not comprehensive) check is this
enough? Too much?
Comments appreciated.

As one who has in the past forgotten to do an install in Chapter 5, only
to discover it haldway through chapter 6. I think this is an excellent idea.
I would also suggest doing a "wc -n" on the file produced as an initial
indication of success (i.e. if the counts wrong, go look for what you missed
