It seems dune 3.0 can not be bootstrapped anymore if there is just an ocaml compiler.

I’m running `ocaml configure.ml && ocaml bootstrap.ml`, then declare `./dune.exe` as `dune` by putting it first in `PATH`.

With [2.9](https://build.opensuse.org/package/show/openSUSE:Factory/ocaml-dune) the next step is to build everything with `dune build --for-release-of-packages=dune,dune-action-plugin,dune-build-info,dune-glob,dune-private-libs @install`. This works because there are no extra dependencies. `dune-configurator` is a separate package, because it depends on `csexp`.

With 3.0 this can not be done because things depend on “leaf” packages such as csexp and pp, which in turn require dune for building.

Is there a way to serialize the build of dune.git again?

You can see the steps done to build dune in opam with nothing but the ocaml compiler here:
