Как добавить параметр «Настройка прошивки» в grub

El enfoque que sigo es simplemente reescribir kill-linepara usar delete-regionen lugar de kill-region. Las funciones kill-regiony delete-regionson ​​casi las mismas. La gran diferencia es que el primero guarda lo que se elimina en el anillo de eliminación. Este último no. Reescribir la función con este reemplazo conserva el comportamiento exacto de kill-linesin efectos secundarios.

(defun my/kill-line (&optional arg)
  "Delete the rest of the current line; if no nonblanks there, delete thru newline.
With prefix argument ARG, delete that many lines from point.
Negative arguments delete lines backward.
With zero argument, delete the text before point on the current line.

When calling from a program, nil means \"no arg\",
a number counts as a prefix arg.

If `show-trailing-whitespace' is non-nil, this command will just
delete the rest of the current line, even if there are no nonblanks
there.

If option `kill-whole-line' is non-nil, then this command deletes the whole line
including its terminating newline, when used at the beginning of a line
with no argument.

If the buffer is read-only, Emacs will beep and refrain from deleting
the line."
  (interactive "P")
  (delete-region
   (point)
   (progn
     (if arg
         (forward-visible-line (prefix-numeric-value arg))
       (if (eobp)
           (signal 'end-of-buffer nil))
       (let ((end
              (save-excursion
                (end-of-visible-line) (point))))
         (if (or (save-excursion
                   ;; If trailing whitespace is visible,
                   ;; don't treat it as nothing.
                   (unless show-trailing-whitespace
                     (skip-chars-forward " \t" end))
                   (= (point) end))
                 (and kill-whole-line (bolp)))
             (forward-visible-line 1)
           (goto-char end))))
