For example, OCaml without ocamlbuild could be proposed as a package only available above some OPAM version (1.2.2 ?), and that version would automatically add an ocamlbuild dependency to every package, except if it has an "ocamlbuild: false" header (or something like that). I am not saying it is the best solution, but changing 4000 packages seem even worse for me. I presume that, most of the time, it is possible to fix such problems in opam rather than in opam-repository.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">(2) Changes in external configurations that affect some systems that<br>

First, it is always good to discuss such changes, just for developers to learn about platforms' specificities that they were not aware of. If you don't do that, you will fix a version, and the next version will be broken again. Second, you are mixing "repo maintainers" and "package maintainers". Maybe developers don't have to know about specific platforms (although they are probably using some platform specific thing otherwise no change would be needed), about here, we are discussing about what package maintainers are supposed to know, or to learn. Package maintainers, as in Debian, are not the authors, they are the people who decide to take responsibility for making a package public on OPAM. On the contrary, repo maintainers are only in charge of maintaining the global consistency of the repository, deciding when there is a conflict between package maintainers, and so on. The whole point of this discussion is to prevent repo maintainers from acting as package maintainers, so this distinction is important !</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
