+1 for buildroot. I've used it both professionally and on personal projects. All of my rpi projects run on tiny buildroot images (usually with a single go binary). I love that it produces an image I can write straight to an SD card that is ready to go without me having to plug the RPI into a monitor to configure it. However LFS and BYOL aren't really about making it easy to build a "distro". They really are about learning how all the pieces fit together.
