Worked on the mendersoftware/mender repository to deliver a feature integrating a dedicated data directory service into the deployment process. This involved introducing the mender-data-dir.service file and making its installation optional through a configurable CMake variable, allowing for greater flexibility in deployment scenarios. Dependencies in related service files, such as mender-authd.service and mender-updated.service, were updated to reference the new service, improving clarity and maintainability. The work focused on build system configuration and systemd service management, utilizing C++ and shell scripting to streamline data directory handling and reduce friction during installation and updates across the Mender stack.
