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 6: GCC Pass 2
|
|
# ============================================================================
|
|
# Purpose: Rebuild GCC with the temporary toolchain. This produces a
|
|
# compiler that runs on the target and generates code for the target.
|
|
# Unlike Pass 1, this includes libstdc++, threading, and shared libs.
|
|
# Hardware-specific flags (-march=znver5) are STILL not applied here;
|
|
# they come when we build the final native GCC in the chroot.
|
|
# Inputs: ${LFS}/sources/gcc-15.2.0.tar.xz + mpfr, gmp, mpc
|
|
# Outputs: Full GCC in ${LFS}/usr/
|
|
# Assumes: All Chapter 5 + Chapter 6 packages (006-021) complete
|
|
# Ref: LFS 13.0 §6.18
|
|
# ============================================================================
