Christopher, I think you do not need (yet) to "destroy" everything again. What
you describe really looks like some missing kernel feature: if a dvd drive is
correctly connected (either through sata or scsi), and all the relevant
options are correctly set when building the kernel, the kernel itself should
create /dev/sr0 in the devtmpfs. Udev is not involved I think.
So compare what you build in or as module for your kernel to what the host
distro has (lsmod on host distro). Note: builtin modules list is at
/lib/modules/<version>/modules.builtin.
For example, from host distro (with the lfs root mounted on $LFS, and VERSION
set to the lfs kernel version string):
------
lsmod | while read module notused; do
if ! find $LFS/lib/modules/$VERSION/ -name ${module}\* > /dev/null; then
if ! grep -q $module $LFS/lib/modules/$VERSION/modules.builtin; then
echo $module is missing
fi
fi
done
------
Any output should be questioned (well, the command above has not been much
tested, too!).
You may want also to start from the host's modules.builtin, instead of lsmod.
