I'd really like a "real" Linux package, as I refuse to run a proprietary binary blob as root.
I don't really care if you make it a .deb or .rpm, I'd even take a simple .tar.gz over what you have now. Or you could package it up into an .AppImage like Prusa Slic3r.
Pretty much any alternative is better than the current installer, as that's not really the way to install stuff on any distro..
