During February 2026, Liar Once developed and delivered the AOSC OS Wallpapers Package featuring fumofumo artwork for the AOSC-Dev/aosc-os-abbs repository. This work involved creating Linux shell scripts and installation metadata to automate the build and packaging process, enabling seamless distribution and user access to new wallpapers. By establishing a packaging-ready workflow, Liar Once enhanced the operating system’s visual customization and supported consistent branding across deployments. The project focused on feature delivery rather than bug fixes, demonstrating depth in build automation and package management using shell scripting. The solution addressed user experience needs by simplifying wallpaper installation and ongoing asset maintenance.
