Worked on modernizing the installation script for the Sonarr/Sonarr repository, focusing on improving compatibility with systemd-based Linux distributions. The update replaced deprecated service status checks with systemd-aware commands, specifically using Shell scripting to implement 'systemctl is-active' for verifying service status and 'systemctl disable --now -q' to stop and disable services during installation and cleanup. This approach aligned the deployment process with current system administration practices, reducing installation and upgrade failures while simplifying ongoing maintenance. The work demonstrated practical application of DevOps principles and Shell scripting expertise, delivering a more reliable and maintainable installation workflow for modern Linux environments.
