Lars Tangvald developed rootless Debian and Ubuntu packaging build support for the percona/percona-server repository, focusing on enhancing security and compatibility with modern distribution policies. By modifying the CMake-based build system and Debian packaging scripts, Lars removed explicit root ownership changes, enabling package builds to run without elevated privileges. This approach addressed compatibility issues with newer Ubuntu versions and allowed continuous integration pipelines to operate without root access, reducing maintenance overhead. Leveraging expertise in build systems and Debian packaging, Lars delivered a distro-friendly solution that aligns with best practices and prepares the packaging process for broader deployment across Debian and Ubuntu ecosystems.
