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
Why would PKGBUILD solve the issue? The packaging issues are still the same, as every distro has different package names, revisions and not all packages in their repository. The dependencies are not solved with this.
If at all, you want to use Gentoo’s ebuild system, which can be seen as some kind of superset of PKGBUILDs. I guess one could write a Python script that “dumbs down” ebuild scripts to PKGBUILDs for simple packages (excluding complex stuff like kernel, KDE, …). The main challenge, as pointed to before, would be maintaining a table mapping package names between distributions in order to get the dependencies right.
