First:
Sorry, the above is completely wrong: find exits with 0 code even when it does
not find a file (if no error occurred). A possible command is:
------
lsmod | while read module notused; do
if [ -z "$(find $LFS/lib/modules/$VERSION/ -name ${module}\*)" ]; then
if ! grep -q $module $LFS/lib/modules/$VERSION/modules.builtin; then
echo $module is missing
fi
fi
done
------
Second: I understand that you have no way to start a distro, but you have a
debian dvd with an installer, don't you? I think you can start in "rescue
mode" (avoid graphical mode), and execute a shell in the installer
environment. Then mount the lfs drive (maybe you'll need to start some lvm
modules), set $LFS and $VERSION, then type the command above (no way to
copy-paste in this case).
