#!/usr/bin/env bash
# restore-dgx-services.sh — Restore non-essential services on a DGX node.
# Brings back the services stopped by stop-dgx-services.sh. Machine-specific
# (DGX), not model-specific.
#
# Baked into the sm121 binary at compile time (see src/builtin_scripts.rs);
# recipes reference it by alias `restore_dgx_services` in an `after_stop` list.
# The launcher uploads and runs it via SSH on each node.
