Complete from-scratch Linux distribution targeting AMD Ryzen 9 9950X3D + NVIDIA RTX 5090 on ASUS ROG CROSSHAIR X870E HERO. Deliverables: - dpack: custom package manager in Rust (3,800 lines) - TOML package parser, dependency resolver, build sandbox - CRUX Pkgfile and Gentoo ebuild converters - Shared library conflict detection - 124 package definitions across 4 repos (core/extra/desktop/gaming) - 34 toolchain bootstrap scripts (LFS 13.0 adapted for Zen 5) - Linux 6.19.8 kernel config (hardware-specific, fully commented) - SysVinit init system with rc.d service scripts - Live ISO builder (UEFI-only, squashfs+xorriso) - Interactive installer (GPT partitioning, EFISTUB boot) - Integration test checklist (docs/TESTING.md) No systemd. No bootloader. No display manager. Kernel boots via EFISTUB → auto-login → dwl Wayland compositor. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# DarkForge Linux — Phase 0, Chapter 5: Glibc (Cross-compiled)
|
|
# ============================================================================
|
|
# Purpose: Cross-compile the GNU C Library (glibc) for the target system.
|
|
# This is the core C library that every program on the final system
|
|
# will link against. After this step, we can compile programs that
|
|
# actually run on the target.
|
|
# Inputs: ${LFS}/sources/glibc-2.43.tar.xz, glibc-2.43-fhs-1.patch
|
|
# Outputs: Glibc installed to ${LFS}/usr/lib/, ${LFS}/usr/include/
|
|
# Assumes: Binutils Pass 1 + GCC Pass 1 + Linux Headers complete
|
|
# Ref: LFS 13.0 §5.5
|
|
# ============================================================================
