+# The releng profile already ships official archiso mkinitcpio hooks at
+# $PROFILE/airootfs/usr/lib/initcpio/{hooks,install}/archiso.
+# Do NOT overwrite them — the official hooks handle uname -m arch detection,
+# correct squashfs paths, all required modules/binaries, and mount_handler
+# wiring. Our simplified custom hooks were causing "sbin/init not found".
