+# Role: System-Maintenance-Lock
+
+## Overview
+The `system-maintenance-lock` role is a critical part of maintaining the integrity and performance of a system. It ensures that specific services are not interrupted or conflicted with by other system processes. This role is particularly vital during system updates, backups, or other maintenance activities where conflicting processes could cause issues.
+
+## Usage
+This role is used in scenarios where system stability and integrity are paramount, such as during system upgrades, backup processes, or when applying critical patches.
+
+## Created with AI
+Created with ChatGPT. Conversation is [here](https://chat.openai.com/share/a886b86b-8de6-4eca-9fba-e36c9f20d536) available.

-# System Maintenance Service Freezer
-
-## Overview
-This Ansible role is designed to manage system services through freezing (disabling) and defrosting (enabling) actions. It automates the process of managing crucial system services, especially useful for maintenance tasks like backups, cleanups, and updates.
-
-## Monitoring
-To monitor the sucess of the script and the status of systemctl timers execute:
-
-```bash
-watch -n 2 systemctl list-timers
-```
-
-## Role Variables
-- `system_maintenance_services`: List of services to be managed by this role.
-
-## Usage
-Configure the role by defining the required variables. The role creates systemd service files that control the specified services based on the `freeze` or `defrost` actions.
-
-For further details and usage examples, refer to the chat conversation with ChatGPT: [Link to ChatGPT Conversation](https://chat.openai.com/share/212af169-1b57-41df-bd2d-c3d32eb1331b).
-
-## Dependencies
-- `systemd-notifier`: Ensure this role is present for handling service failures.
