Bonjour,
Je viens « de tester » de compiler un noyau Linux en partant des sources de kernel.org 
et cela en créant de packages debian.
Style çà doit bien faire 15 ans je n’ai pas compilé 
Je crois que ce n’est pas conseillé pour « un newbe de la compile » comme moi, mais c’est pour apprendre et, que surtout j’étais sur un kernel 5.x et que j’ai compilé un kernel 6.x - Tout va buguer.
J’ai suivis cette documentation debian - 8.10. Compiling a Kernel en compilant un kernel v6.x que j’ai appelé « ninja » pour Linux kernel version history - Releases 6.x.y - « Hurr durr I’ma ninja sloth » 
J’ajoute ce lien « Kernel Compilation in Debian Linux » et celle-ci « Debian Linux Kernel Handbook »
Comme c’est écrit ici :
Si vous choisissez de compiler votre propre noyau, vous devez en accepter les conséquences : Debian ne peut pas garantir les mises à jour de sécurité pour votre noyau personnalisé. En conservant le noyau fourni par Debian, vous bénéficiez des mises à jour préparées par l’équipe de sécurité du projet Debian.
Préparation :

Pour installer le noyau Linux :
root@vps:~ # dpkg -i linux-libc-dev_6.0.9-1_amd64.deb
root@vps:~ # dpkg -i linux-image-6.0.9-ninja_6.0.9-1_amd64.deb
root@vps:~ # dpkg - i linux-headers-6.0.9-ninja_6.0.9-1_amd64.deb
Puis redémarrer :
root@vps:~ # reboot
Pour se retrouver sur un kernel 6.0.9.
root@vps:~ # uname -a
Linux vps 6.0.9-ninja #1 SMP PREEMPT_DYNAMIC Sun Dec 11 18:34:18 UTC 2022 x86_64 GNU/Linux
Je souhaiterais savoir à quoi servent ces fichiers après avoir lu « Upstream (développement logiciel) (en) , se dit d’un projet logiciel donné qui sert de base à un ou plusieurs autres, qualifiés pour leur part de downstream (comme par exemple le noyau Linux joue le rôle d’ upstream pour les distributions GNU/Linux). »

- linux-upstream_6.0.9-1_amd64.buildinfo
- linux-upstream_6.0.9-1_amd64.changes
- linux-upstream_6.0.9.orig.tar.gz
Donc, j’essaie de re-compiler avec d’autres valeurs dans la « .config » mais quand je relance la compilation du noyeau çà plante.

Note de Moi-même 19h25 :
À la place de «
$(make kernelversion)-1» → → «$(make kernelversion)-2»
il aurait été préférable que je mette «$(make kernelversion)-0.1» → → «$(make kernelversion)-0.2» etc, n’est-ce pas ?
Si vous avez des informations ? Qui peut m’aider ?
Merci.
Romain
À « m’essayer » de faire un module, de le signer, de l’implanter au système et de m’en servir.
Un truc du genre.
