If I understand it correctly, eln-cache is now 'by machine' and if I'd
like to pre-populate the `eln-cache/emacs-30.1-machinehash` I'd have to
use the `comp-abi-hash` to assembly my new eln-cache path and clone my
.eln into there.
native-comp-eln-load-path (as you may set via startup-redirect-eln-cache) appends comp-abi-hash, which is specific to an Emacs build and that includes architecture, compiler arguments, etc. It is host independent.
Do I wish a user option to override `comp-abi-hash` would be available
to the lisp user? Yes. Do I think exposing it is a good idea? No. For
that I believe you guys know better :)
You do not want this.
