Add ability to preserve multiple versions of kernel, dtb, u-boot, headers, and libc packages while maintaining single-version policy for other packages. This enables: - Kernel rollback scenarios by keeping multiple linux-image-* versions - DTB rollback with multiple linux-dtb-* versions - Bootloader flexibility with multiple u-boot-* versions - Development stability with multiple linux-headers-* versions - Library compatibility with multiple libc6/libc-dev versions Changes: - Add KEEP_MULTIPLE_VERSIONS global variable (enabled by default) - Add package name pattern matching for critical packages - Add -m/--multiple-versions command-line option - Enhance deduplication logic to skip removal for matched packages - Update configuration display and help text Note: armbian-bsp packages continue to use single-version policy to avoid dependency conflicts.

Purpose of This Repository
The Armbian Linux Build Framework creates customizable OS images based on Debian or Ubuntu for single-board computers (SBCs) and embedded devices.
It builds a complete Linux system including kernel, bootloader, and root filesystem, giving you control over versions, configuration, firmware, device trees, and system optimizations.
The framework supports native, cross, and containerized builds for multiple architectures (x86_64, aarch64, armhf, riscv64) and is suitable for development, testing, production, or automation.
Looking for prebuilt images? Use Armbian Imager — the easiest way to download and flash Armbian to your SD card or USB drive. Available for Linux, macOS, and Windows.
