This is my question. :-) I am not following closely enough the OCaml development. Well, I thought you knew what previous features is required to compile next compiler. :-) > From what I understand, currently only OCaml 4.07 is bootstrapped with > camlboot in Guix.

Somehow the resulting OCaml 4.07 is considered as “trusted” and I am not sure there is some plan to upgrade camlboot to support more recent OCaml; at least not in the short term, maybe I have misunderstood. 1: <https://10years.guix.gnu.org/static/slides/08-courant.pdf> Cheers, simon
