Need a packaging guide

[cyqsimon]

At this point yarn is independently packaged in almost every Linux distribution, see https://pkgs.org/search/?q=yarn. Hovever today I discovered, to my great surprise,that most if not all of them (including ArchLinux!) are still offering 1.22, which is very odd.

So naturally I submitted issues to the distros I use, and the good people at Fedora replied pretty quickly: https://bugzilla.redhat.com/show_bug.cgi?id=2227706#c1, saying that they "didn't really manage to understand how to build it from source". I linked to them an exampe of how an AUR package did it, but honestly its liberal use of cp -R * worries me. When I looked into the newest release tarball, it confused me whether the entry point should be directly packages/yarnpkg-cli/bin/yarn.js, or should it be scripts/bin/yarn, or should it be scripts/dist-scripts/yarn. I suspect the reason other distros haven't updated might be similar - they don't know what to do.

Therefore I think it would be a good idea for this repo to contain some kind of official documentation/recommendation/guides on how independent packagers should be packaging yarn 3.x. Thank you in advance for your effort.
