Debian UKI

The purpose is automatize building and signing of a Unified Kernel Image on Debian and derivatives after kernel or initramfs update.

Important

The auto-update of this script should be disabled! Make sure to create .disabled file.

Dependencies

Make sure that:

• if running Ubuntu 24.04+, Linux Mint 22+ or Debian 13+, systemd-ukify is installed
• binutils, efibootmgr and systemd-boot-efi packages are installed
• you install the UKI to your EFI configuration

Files

• build-uki.sh is the main script, which builds and signs the UKI.
• 99build-uki is an APT hook to invoke the main script.
• variables.conf.template contains examples variables definitions, and should be copied locally to variables.conf (with any required modifications).

Installation

• install.sh script copies APT hook to its destination, so the script is invoked after updates.

TODO

• find a way to invoke script only on kernel or initramfs update
