Worked on upgrading the Lunar package to version 2.2-r6 within the microcai/gentoo-zh repository, focusing on enhancing build stability and maintainability for Gentoo users. The update involved replacing the previous 2.2-r5 release, introducing new compilation logic, and updating source URIs to streamline the packaging process. Leveraged Bash scripting and Linux package management skills to align the workflow with Gentoo packaging standards. While no explicit bug fixes were recorded, the improved build process aimed to reduce potential failures and deliver the latest Lunar features. The work demonstrated a methodical approach to package maintenance and continuous integration in a Linux environment.
