LinuxBoot

LinuxBoot is a Linux Foundation firmware project that uses a Linux kernel and initramfs as a bootloader, replacing specific firmware functionality such as UEFI DXE. It provides faster, more reliable, and more secure boot processes by leveraging the well-tested Linux kernel for hardware initialization. Core components include u-root (the ramfs builder), the LinuxBoot build system, and the NERF (Non-Extensible Reduced Firmware) heritage from Google.
