* Perform sudo in harmonic * Remove sudo in scripts * A bit more tweaking... * Yay unix * Use curl sh on ci * Preserve environments we require * Fix the yamls * Better explain a run step * Preserve GITHUB_PATH too * Correct trace * Include install-nix.sh in artifacts * Remove unused vars * Use /nix/harmonic for uninstall * Only pass --preserve-env if required * Wait for python server to start * Use a sudo uninstall * Pass verbosity correctly * Pass no-confirm by env * Pass no-confirm by env redux * Hahaha very funny yaml * handle env in no-confirm * Preserve env on ci * Mac stuff
