Dieses Script führt einen automatisch durch die verschiedenen Schritte, die zum Konfigurieren und Kompilieren eines Kernels notwendig sind. Darüber hinaus gibt es auch die Möglichkeit, einen bereits installierten Kernel zu löschen.

Anmerkung: Mittlerweile gibt es eine von Grund auf neugeschriebene Version dieses Scripts. Diese basiert nicht mehr auf dialog und ist dadurch weitaus portabler. Darüber hinaus enthält sie diverse Verbesserungen und wird gegenüber der hier angebotenen Version dringend empfohlen.

• dialog
• alles, was zum Kompilieren und Konfigurieren eines Kernels benötigt wird wie gcc, make, libncurses5-dev
