How to get a runner on OCaml 5.2.1?

[hannesm]

I don't quite understand, but I'd like to get a Mirage CI that uses OCaml 5.2.1. Now, it seems to use

let pp_ocaml f = function V4_14 -> Fmt.pf f "4.14" | V5_2 -> Fmt.pf f "5.2"

let pp_exact_ocaml f = function
  | V4_14 -> Fmt.pf f "4.14.2"
  | V5_2 -> Fmt.pf f "5.2.1"

let pp_system f { ocaml; os } = Fmt.pf f "%a-ocaml-%a" pp_os os pp_ocaml ocaml
let spec t = Spec.make @@ Fmt.str "ocaml/opam:%a" pp_system t

So, ocaml/opam:...-5.2 -- which is an image with the OCaml 5.2.0 compiler. Is there as well a -5.2.1 tag that we can use?

Hi @hannesm,

You'll need to update the Linux distributions as well see https://github.com/ocurrent/mirage-ci/blob/main/src/lib/common/platform.ml#L11 We stopped building new images for those platforms so they will never get OCaml 5.2.1.

Depending on what OCaml versions and Linux distributions you want #50 might work.
