	After signing the Linux Kernel modules with the ephemeral key, proceed by compressing the Kernel modules with xz to reduce the final ISO image size. Initial tests have shown a size reduction by 60MiB.
2024-09-25	T861: sign all Kernel modules with an ephemeral key	Christian Breunig
	The shim review board (which is the secure boot base loader) recommends using ephemeral keys when signing the Linux Kernel. This commit enables the Kernel build system to generate a one-time ephemeral key that is used to: * sign all build-in Kernel modules * sign all other out-of-tree Kernel modules The key lives in /tmp and is destroyed after the build container exits and is named: "VyOS build time autogenerated kernel key". In addition the Kernel now uses CONFIG_MODULE_SIG_FORCE. This now makes it unable to load any Kernel Module to the image that is NOT signed by the ephemeral key.
