Worked on enhancing the Ubuntu installation process for the sched-ext/scx repository by focusing on documentation improvements and build system reliability. Updated the installation guide to include libbpf-dev as a development dependency, ensuring necessary headers are available for building C schedulers. Revised instructions to align with Ubuntu 25.10, removing outdated PPA references and deprecated flag usage, which directs users toward stable releases and kernels. These changes, implemented using Markdown and Shell scripting, aimed to streamline onboarding, reduce installation errors, and minimize support overhead. The work demonstrated attention to detail in documentation and dependency management, contributing to a smoother developer experience.
