Thanks — rpm support is welcome. One blocker: the Linux branch of install.sh no longer goes through npm run build, so it loses the umask 022 added in #281. Under a restrictive umask the .desktop file, package root and a few resources end up without world-read, for both deb and rpm. Could you add umask 022 before the build commands in the Linux branch?

Smaller things:

• Check for rpmbuild (rpm-build) before taking the rpm path, with a hint if it's missing — on a plain Fedora box fpm fails with an unclear error.
• --no-install is Linux-only and undocumented; please mention it (or make it a no-op with a message on macOS).
• Could you confirm from a Fedora install that the rpm shows up in the app menu and opens parallelcode:// links?
