On my machine, camlboot takes ~3h to build. Then ocaml-4.07-boot takes ~30s. Last there is no meaningful difference between building ocaml-4.07 using the embedded ocamlc and ocamlex binaries and using the binaries from ocaml-4.04-boot; both ~6m. I have check that camlboot, ocaml-4.07-boot and ocaml-4.07 build reproducibly with =E2=80=99--check=E2=80=99. They do. > As a result, we have identical files for this bootstrap and the > unbootstrapped OCaml (up to output store paths and hash of some files > that get embedded in native files, which differ because of the > different output path). At first look, yes. :-) Modulo the minor comments I made, patches LGTM! Thanks. Well, the next steps are to build ocaml-4.09 and ocaml-4.11 using the previous ocamlc and ocamlex version, right? Then, it implies rebuild all the OCaml packages, right? It could be done in this core-updates cycle, WDYT? Cheers, simon
