Worked on improving NetBox upgrade reliability within the srid/nixpkgs repository, focusing on NixOS deployments. Addressed issues with outdated static files by ensuring the upgrade process clears old assets using collectstatic --clear, preventing stale UI elements and broken object relations. Enhanced the upgrade workflow by implementing symlink-based checks to detect configuration or plugin changes, prompting users to upgrade when necessary. Utilized Nix and DevOps skills to automate these processes, streamlining system administration and configuration management. These changes increased upgrade reliability and uptime, reduced misconfigurations, and simplified maintenance for operators managing NetBox on NixOS systems.
