[$] Pulling Linux up by its bootstraps

A bootstrappable build is one that builds existingsoftware from scratch - for example, building GCC without relying on an existingcopy of GCC. In 2023, the Guix projectannounced that the project had reduced the sizeof the binary bootstrap seed needed to build its operating system to just 357-bytes -not counting the Linux kernel required to run the build process. Now, thelive-bootstrap projecthas gone a step further and removed the need for an existing kernel at all.
