Make Your System Firmware Faster, More Flexible and Reliable with LinuxBoot
summary
LinuxBoot replaces proprietary firmware by embedding a Linux kernel (handed off from coreboot) plus u-root/systemboot userland to initialize devices, enable boots under 10 seconds on stripped images, and perform secure HTTPS netboot with signature verification. Facebook shows probe-launcher and yard images for robust provisioning, demonstrates tcpdump-level debugging on firmware, and runs this on Open Compute Project hardware (wedge100s demo), cutting vendor blob cycles and shortening bug-to-fix from months to days.
