> distros should package for themselves. You just distribute your sources.

Is Devault basically saying that the application developer should just throw their source code over the wall and hope that other parties notice and figure out how to build it correctly? I would find that model of software distribution unsatisfying as a developer because merely distributing a source tarball and leaving the rest to middlemen makes it difficult for me to predict how my users will experience the final product. Even if my product is fully open source and free to fork, it's my reputation on the line when things don't work as intended. I would prefer to establish a more direct relationship with my users; to personally build and test my software in all environments that I support; and to hear directly from users whenever they experience problems.

I think that everyone who is worrying about that wants to apply corporate thinking on the open source model. Meaning they want to be a special thing where everything is supposed to be interchangeable. Just yesterday, I was compiling a program that hard depends on the GNU C library for just 2 functions and not even critical one. To be fair, the author said that they only test on Debian.

While the linux world may be fragmented, the true differences are mostly minimal (systemd vs other init system, glibc vs musl, networking manager,…) So it’s possible to decouple yourself from these concerns if you want to. But often the developer hard depends on decision made by their preferred distro team, and create a complicated build script that only works there.

I don't know what Devault says, but here is my opinion: do not ship something you don't understand/test/use yourself.

Distros should not package random open source projects they don't use/understand, and developers should not package their project for distros they don't use/understand. For both, it's like shipping untested code and the conclusion is always going to be "you should all run the same system I do" or "we should all have the exact same system, let's implement Flatpak".

Developers should package their project for the distros they support (often that's just Ubuntu). Random people should package the open source projects they want to use in their distro of choice (the more popular the distro, the higher the chance that someone else has done it already). All that under the supervision of distro maintainers.
