Re: Packaging OCaml repositories that define multiple packages?

The importer will not support such a package. As you say, it wants to build them separately because they are separate opam packages. So, either we build them separately too, or we build all at once.

If we build all at once, that's fine. You could name the package ocaml-mirage and not use any #:package argument. Dune will then build all packages from the repository.

One issue with that is that the importer will not know about it and will try to import subpackages again whenever a packages depends on it, instead of using ocaml-mirage.

I don't like the alias solution, though it should work, since the importer would see them.
