Thanks so much > in advance As I understand it, the Linux kernel live patches aren't possible to just produce automatically, it requires a team with enough Linux kernel knowledge to make it work. Debian doesn't have a team doing that yet. I don't think that Linux kernel live patches are very suitable for Debian unstable/sid because the major version of Linux in sid changes fairly often, although there are stable updates in sid, but those are fairly frequent. So the service would mostly be for stable/oldstable. Probably the best people in Debian to do that are the LTS team, who provide support for old Debian releases, including for Linux, the LTS team are paid by external sponsors, so they might have the financial resources needed to make this a reality for Debian. Please contact them about this service idea. https://lists.debian.org/debian-lts/ Also, I think that the base Linux kpatch tools are open source, but the infrastructure that RedHat/SUSE/Canonical use to provide them are not. However, I think the Gentoo folks do have some open infra code. https://github.com/dynup/kpatch https://wiki.gentoo.org/wiki/Elivepatch https://wiki.gentoo.org/wiki/Live_patching https://github.com/gentoo/elivepatch-server https://github.com/gentoo/elivepatch-client -- bye, pabs https://wiki.debian.org/PaulWise
