Unified Kernel Images

A Unified Kernel Image (UKI) is a combination of an UEFI boot stub, a Linux kernel, and further (optional) resources&#xA;like an initrd, all combined into a single UEFI image. This file can either be directly invoked by the UEFI firmware bootloader&#xA;or by a bootloader like rEFInd or an OS&rsquo; bootloader.
