/me played with buildroot too: https://gitlab.com/kraxel/br-kraxel userspace systemd does take much time indeed, but buildroot allows to build with busybox. You can also easily include more stuff like pciutils to run tests. bootloader support in buildroot varies much depending on architecture. Modern standard platforms (x86, arm) are no problem, but for older/exotic platforms (sparc for example) you can't easily generate bootable disk images. take care, Gerd
