During February 2025, Marek Belisko enhanced the pantavisor/meta-pantavisor repository by improving the build script’s cross-shell compatibility. He modified the build_with_container.sh script, changing its shebang from /bin/bash to /bin/sh, which allowed the script to run reliably across a wider range of environments without altering its core functionality. This adjustment addressed potential build failures in diverse CI and onboarding scenarios, streamlining the development workflow. Marek applied his expertise in shell scripting and build scripting, focusing on containerized build processes and careful change management. The work demonstrated a targeted, low-risk approach to increasing reliability without introducing regressions or unnecessary complexity.
