The author presents a unique method of embedding a user-space program directly into the Linux kernel image to be executed from there. While this may seem unconventional, it can be useful in scenarios where the kernel needs to run helper programs. By using the User Mode Driver API and assembly files, a program can be included in the kernel image without relying on the root file system. The example provided uses a Go program due to its static linking and file system independence. Although the practical applications may be limited, this approach offers new possibilities and can be beneficial in certain situations.
