Build System Analysis for Kernel Development and Customization
summary
Compares concrete kernel workflows and shows what actually builds and boots: uses Fedora (fedpkg, SRPMs / KernelArc source tree) to produce RPMs and apply numbered patches, with make config/merge_config.sh for fragments; uses Buildroot (make linux, global patch list, absolute fragment paths) which builds an image and QEMU boots showing init prints but can silently ignore missing patches and needs manual header fixes; uses Yocto (devtool workspace, kernel-meta, auto-generated fragment) where patches and fragments build, QEMU confirms module loaded; notes 80–100 new config items during merge windows.
