Configuration files and scripts for building a tiny Linux + Busybox distribution. Intended for use as a recovery OS in BIOS chips on Coreboot and Libreboot devices.
Currently, the build script will create a kernel and initrd with the default configurations for both Linux and Busybox. This runs, however it is around ~14MB total. In order to store on the BIOS chip of most Coreboot-supported systems, the total size must be anywhere between 2MB and 10MB. In order to achieve this, certain unnecessary Busybox programs and Linux drivers must be disabled.
