@eggsyntax there’s additional code being run in packages.el of the clojure layer, which is probably overriding your code

Hmm. So possibly I need to do it as (with-eval-after-load 'clojure-mode ...)?

I may not be understanding the full order in which code is running at startup. I thought it was load libs -> run lib code -> user-config (maybe with other stuff in between, certainly with stuff before & after)

not sure myself, but try it without the with-eval-after-load? the user-config section is executed right at the end of the spacemacs startup …

Worth a try!

Nah, no such luck.

Nor (with-eval-after-load 'clojure-mode ...)

The keymapping which overrides it is defined in cider-repl.el, which is why it seemed like with-eval-after-load 'cider-repl-mode-map would do it.
