Module Overview

The kernel module provides comprehensive Linux kernel management capabilities, including kernel source downloading, configuration, compilation, and packaging. This module is essential for creating custom boot environments tailored for specific use cases, including minimal attack surfaces, virtualization support, and cloud-specific features.

The module handles the complex process of building Linux kernels with specific configurations optimized for various scenarios. It manages multiple kernel versions simultaneously and creates kernel artifacts ready for distribution and deployment across different platforms.

Functionality

Linux kernel source management: Download kernel sources from official repositories, verify integrity, and manage multiple kernel versions simultaneously
Kernel configuration and building: Apply custom kernel configurations, compile with optimized flags, and build kernel modules for specific hardware and virtualization scenarios
Module extraction and packaging: Extract built kernel modules into deployable packages and create kernel artifacts for distribution
Custom kernel optimization: Build kernels with specific configurations for virtualization, containers, or cloud environments
Version management: Track and manage multiple kernel versions with their respective configurations
Build artifact management: Organize and manage kernel build artifacts including vmlinuz, System.map, and module trees
