Understanding, Building and Researching Minimal (and not so minimal) Linux Systems
summary
Builds a bootable minimal Linux by compiling kernel 5.6.37, producing a tiny vmLinux and a static BusyBox static binary, assembling an initramfs cpio+gzip image and running it under QEMU/KVM. Covers .config fragments, built-in vs. M modules, module-install layout, frame buffer vs. serial consoles, pSplash for bootsplash, and Yocto as a full build system. Results boot successfully in QEMU with a ~2–8 MB initramfs and working shell and basic tools.
