## V37 2026-03-20 22:30:00
**Use Danish GNU mirror and add loopback disk setup script**
### Changes:
- Updated `toolchain/scripts/000a-download-sources.sh`:
- Switched all GNU package URLs to use `http://ftp.klid.dk/ftp/gnu` mirror
(faster from Denmark than ftp.gnu.org)
- Added `GNU_MIRROR` variable at top for easy mirror switching
- Non-GNU packages (kernel, mpfr, gmp, xz, zstd, perl, python, etc.) still
use their canonical upstream URLs
- Added `toolchain/scripts/000-setup-disk.sh`:
- Creates a 50GB loopback ext4 filesystem at /opt/darkforge.img
- Mounts it at /mnt/darkforge — acts exactly like a real partition
- Uses fallocate for instant allocation (no slow dd)
- Includes remount instructions and fstab entry
- Safe: no repartitioning needed, uses free space on root
- Updated `toolchain/scripts/000-env-setup.sh`:
- Improved error message to point users to 000-setup-disk.sh
### Plan deviation/changes:
- Using loopback file instead of a dedicated partition (user has no spare
partition but has 1.5TB free on root)
### What is missing/needs polish:
- None

# DarkForge Linux — Phase 0: Create LFS Build Partition (Loopback)
# ============================================================================
# Purpose: Create a loopback ext4 filesystem for the LFS build environment.
# This avoids repartitioning and uses free space on your root drive.
# The loopback file acts exactly like a real partition.
# Inputs: None (uses defaults below, override via environment)
# Outputs: 50GB ext4 filesystem mounted at /mnt/darkforge
# Assumes: Running as root, ~50GB free on root filesystem
# ============================================================================
