During June 2025, Zhangkun focused on enhancing service startup management within the linuxdeepin/dde-daemon repository. He implemented granular control over system service startup behavior, allowing services such as dde-authority and dde-backlight-helper to be started explicitly on demand rather than automatically at boot. This approach, developed using Shell scripting and leveraging DevOps and system administration skills, reduced unnecessary resource consumption and improved system stability during upgrades. By introducing startup flags and clarifying intent in commit messages, Zhangkun laid the groundwork for future startup policy governance, resulting in a more maintainable codebase and more predictable service behavior during system transitions.
