make-launchd.sh

#!/bin/sh
# make-launchd.sh — build + install launchd from src/ on a system that
# already has the GNUstep system domain at /System/Library/.
#
# Standalone per plan §8.8: build.sh calls this at livecd-build time,
# and downstream consumers (e.g. gershwin-on-freebsd's chroot) can
# clone the repo and call this directly to drop launchd onto an
# existing /System/Library/ tree.
#
# Usage:
#   make-launchd.sh [--prefix=/path]
#
# --prefix targets a chroot install (DESTDIR). Default empty (host).
