Open Source Summit India 2026

Modern server infrastructure is frequently limited by proprietary UEFI firmware—a slow, unauditable "black box" that introduces security risks and operational bloat. This session presents a transformative alternative: a lean, open-source boot stack pairing coreboot with LinuxBoot to achieve rapid boot times .
We will explore the technical synergy between these two powerhouses. coreboot handles the critical "early wake-up" of silicon—including DRAM, CPU, and PCI initialization—before handing control to LinuxBoot. By embedding a minimalist Linux kernel directly into the firmware flash, LinuxBoot replaces complex UEFI DXE phases with battle-tested upstream drivers. Attendees will learn the conceptual foundations of the u-root Go-based userland for flexible networking and storage logic, alongside the kexec system call for seamless transitions to the production OS. This session provides a roadmap for building vendor-neutral, high-performance infrastructure from the reset vector up.
