Cryolitia worked on the linuxdeepin/dde-session-shell repository, focusing on improving the reliability and packaging quality of the Deepin Desktop Environment session shell. During this period, Cryolitia addressed a critical issue where the Deepin Greeter install script failed to start after system build due to missing executable permissions. By reconfiguring the CMake-based build system and switching the packaging method from FILES to PROGRAMS, Cryolitia ensured the script was installed with the correct permissions, enabling automatic startup post-build. This packaging-level change reduced manual intervention and improved deployment consistency, demonstrating a solid grasp of build system configuration and Linux packaging practices.
