You know what I just realised? These “universal formats” were created to make it easier for developers to package software for Linux, and there just so happens to be this thing called the Open Build Service by OpenSUSE, which allows you to package for Debian and Ubuntu (deb), Fedora and RHEL (rpm) and SUSE and OpenSUSE (also rpm). And then the dudes that do AUR packages can take a deb package and write a PKGBUILD that installs it on Arch and Artix. I think I just solved the universal packaging problem.

And maybe we can get OBS to add PKGBUILD support…

Also, feel free to let me know what you think about it as I’m genuinely curious: did I miss anything obvious? Thanks
