Hello Pierre,
I managed to burn a debian live dvd by "burning" a live dvd onto my 8 gig usb
stick.
The results of your command are:
root@debian:/var/lib/dpkg# 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

I need to add that debian is running the 4.x series of kernel.
I have no idea if the "is missing" modules would be causing the kernel to not
create /dev/sr0 or not. When I attempted to create the dev using mknod, after
it was created, it gave an error that /dev/sr0 is not a valid block device, so
that did not solve anything unfortunately. I did try the sed for the udev
rule, and that also made no difference.
There is no /dev/cdrom created either, so I have absolutely no idea where to go
from here.
I have most of my required modules installed directly into the kernel rather
than as a seperate module that can be inserted using insmod.
Regards,
Christopher.
