Yes, indeed, and that's because --batch now outputs a backtrace, which
loads debug.el, and since we're in a chroot, Emacs can't load that file?

So I disabled that, and got the real error:

Test bytecomp-tests--dest-mountpoint condition:
    (ert-test-failed
     ((status . 255)
      (output . "Creating directory with prefix: Read-only file system, 
/home/larsi/src/emacs/trunk/test/emacs-testsuite-\n")))

And...  that's from here?

      ;; When $HOME is set to '/nonexistent' means we are running the
      ;; testsuite, add a temporary folder in front to produce there
      ;; new compilations.
      (when (equal (getenv "HOME") "/nonexistent")
        (let ((tmp-dir (make-temp-file "emacs-testsuite-" t)))
          (add-hook 'kill-emacs-hook (lambda () (delete-directory tmp-dir t)))
          (push tmp-dir native-comp-eln-load-path))))

Hm...  is there no way to disable all the nativecomp stuff?
