I downloaded from: https://packages.debian.org/sid/linux-source-6.10 the kernel source and compiled it creating the deb files at the end: linux-headers-6.10.6_6.10.6-2_amd64.deb linux-image-6.10.6_6.10.6-2_amd64.deb linux-libc-dev_6.10.6-2_amd64.deb
I inserted them inside the packages.chroot folder then at startup to create the build I launch sudo lb clean sudo lb config --linux-packages none sudo lb build but the problem is that when it is starting to create the iso, it stops and goes into error as if the kernel inserted on packages.chroot does not work in fact it does not put it by default. Is there any procedure to integrate it?
