+echo "📋 Solution Summary:"
+echo "-------------------"
+echo "✅ Enhanced __start_init_scripts function:"
+echo "   - Better error handling with immediate container exit on service failures"  
+echo "   - Improved service verification after startup"
+echo "   - Detailed logging and status reporting"
+echo "   - Proper cleanup of stale PID files on restart"
+

+echo "✅ Enhanced __no_exit function (service supervisor):"  
+echo "   - Continuous monitoring of all services"
+echo "   - Configurable failure thresholds (default: 3 failures per service)"
+echo "   - Container termination when critical services fail"
+echo "   - Periodic status logging"
+echo "   - Graceful cleanup on container shutdown"
+
+echo ""
+echo "✅ Fixed container restart issues:"
+echo "   - Stale PID files are cleaned up on restart"
+echo "   - Services restart properly after container restart"
+echo "   - No more 'zombie' containers that appear running but have dead services"
+
+echo ""
+echo "🔧 Key Improvements Made:"
+echo "------------------------"
+echo "1. Modified entrypoint.sh to clean stale PIDs on restart"
+echo "2. Enhanced __start_init_scripts with better error handling and exit codes"

+echo "⚙️  Configuration Options:"

+echo "• SERVICE_CHECK_INTERVAL: How often to check services in seconds (default: 30)"  
+echo "• MAX_SERVICE_FAILURES: Max failures before terminating container (default: 3)"
+
+echo ""
+echo "🎯 Expected Behavior:"
+echo "--------------------"
+echo "• Container starts and initializes all services"
+echo "• If any service fails to start, container exits immediately"  
+echo "• Once running, supervisor monitors all services continuously"
+echo "• If any service dies and exceeds failure threshold, container exits"
+echo "• On container restart, all services start fresh (no stale state)"
+echo "• Orchestrator (Docker/Kubernetes) can restart failed containers automatically"
+
+echo ""
+echo "📝 Files Modified/Created:"

+echo "• rootfs/usr/local/bin/entrypoint.sh (PID cleanup logic)"
+echo "• rootfs/usr/local/etc/docker/functions/entrypoint.sh (enhanced functions)"
+
+echo ""
+echo "🚀 To apply this solution to all repositories:"
+echo "---------------------------------------------"
+echo "1. Copy the enhanced functions file to each repo's rootfs/usr/local/etc/docker/functions/"
