Worked on enhancing the percona/percona-server repository by implementing rootless Debian and Ubuntu packaging build support. This involved modifying the CMake-based build system to remove explicit root ownership changes, allowing packaging builds to run without elevated privileges. The approach improved security and compatibility, particularly with newer Ubuntu versions that restrict root builds, and addressed Bug#37765153. By aligning the packaging process with Debian policies, the work enabled continuous integration to operate without root access and reduced maintenance overhead. Demonstrated skills in build systems and Debian packaging, contributing to a more distro-friendly process and preparing for broader deployment across Debian and Ubuntu ecosystems.
