(I've also tried to adapt call-with-error-handling instead - but for some reason it never disables the repl prompt)

The safe way (an exception could have fewer arguments that what’s above)
is to write something like:

      (catch #t
        (lambda ()
          (primitive-load to-load))
        (const #t)  ;nothing
        (lambda (key . args)
          (print-exception (current-error-port)
                           (stack-ref (make-stack #t) 1)
                           key args)
          (exit 1)))

Could you check if it works for you?

That’s a good idea.  Could you make it a separate commit?

Thanks,

I think it's better if, instead, we give the initrd (at least) a new parameter enter-repl-on-errors?, defaulting to #t, which can be used by marionette-operating-system to disable the REPL.

I tried to do that like this:

But I get a resolve-variable error about enter-repl-on-error.  Why?
