Security

Speculative-execution mitigations enabled. No build-CPU-specific tuning: the kernel runs on any amd64 machine.

Install the kernel on Debian 13

Already included in AuxiNuxOS. On an existing Debian 13 system:

  1. 1

    Add the repository key

    sudo wget -O /usr/share/keyrings/auxinuxos-archive-keyring.gpg \
  https://dep.auxinux.ca/AUXINUXOS/auxinuxos-archive-keyring.gpg
  2. 2

    Declare the source

    echo 'deb [signed-by=/usr/share/keyrings/auxinuxos-archive-keyring.gpg arch=amd64] https://dep.auxinux.ca/AUXINUXOS kernel main' \
  | sudo tee /etc/apt/sources.list.d/auxinuxos-kernel.list

    Never use [trusted=yes].

  3. 3

    Install and reboot

    sudo apt update && sudo apt install kernel-auxinuxos
sudo reboot

    The previous kernel remains available in GRUB, under “Advanced options”.

The series is pinned to 7.2: the kernel follows 7.2.x fixes without jumping to 7.3 on its own. The kernel-dev channel (kernel-auxinuxos-dev package) can coexist with the production kernel; you choose at boot. OpenZFS is available on request through DKMS (openzfs-zfs-dkms).
