# DarkForge Linux — Phase 0, Chapter 7: Run All Chroot Build Scripts
|
|
# ============================================================================
|
|
# Purpose: Enters the chroot and runs scripts 024-031 in sequence.
|
|
# This is a convenience wrapper — run it on the HOST as root,
|
|
# AFTER 023-chroot-setup.sh has mounted virtual filesystems.
|
|
# Usage: sudo bash /mnt/darkforge/sources/toolchain-scripts/023a-chroot-build-all.sh
|
|
# Inputs: LFS environment variable (default: /mnt/darkforge)
|
|
# Outputs: Completed chroot tools (gettext, bison, perl, python, texinfo, util-linux)
|
|
# Assumes: 023-chroot-setup.sh already ran, virtual filesystems mounted
|
|
# ============================================================================
