# DarkForge Linux — Phase 3, Chapter 8.29: Shadow
# ============================================================================
# Purpose:  Build Shadow, which provides tools for user and group management:
#           useradd, userdel, usermod, passwd, su, login, etc.
#           CRITICAL: Disable systemd support — we use SysVinit only.
# Inputs:   /sources/shadow-4.17.4.tar.xz
#           libxcrypt already installed
# Outputs:  User/group management tools in /usr/bin, /usr/sbin, /etc/default
# Ref:      LFS 13.0 §8.29
# Notes:    NO systemd-enable, NO logind, NO PAM modules for systemd
# ============================================================================
