En la versi\u00f3n de Fedora 38 se propone implementar la primera etapa de transici\u00f3n hacia un proceso de arranque modernizado, previamente sugerido por Lennart Poettering, para organizar un arranque verificado completo que abarque todas las etapas, desde el firmware hasta el espacio del usuario, y no solo el n\u00facleo y el cargador de arranque. La propuesta a\u00fan no ha sido considerada por el comit\u00e9 FESCo (Fedora Engineering Steering Committee), que es responsable de la parte t\u00e9cnica del desarrollo de la distribuci\u00f3n Fedora. <\/p>\n

Los componentes para implementar la idea propuesta ya est\u00e1n integrados en systemd 252 y se reducen al uso de una imagen unificada del n\u00facleo UKI (Imagen Unificada del N\u00facleo) en lugar de la imagen initrd, que se forma en el sistema local al instalar el paquete del n\u00facleo y que es generada en la infraestructura de la distribuci\u00f3n y firmada digitalmente. UKI combina en un solo archivo el controlador para cargar el n\u00facleo desde UEFI (UEFI boot stub), la imagen del n\u00facleo de Linux y el entorno del sistema initrd que se carga en memoria. Al invocar la imagen UKI desde UEFI, se ofrece la posibilidad de verificar la integridad y autenticidad mediante la firma digital, no solo del n\u00facleo, sino tambi\u00e9n del contenido de initrd, cuya verificaci\u00f3n es importante ya que en este entorno se extraen las claves para la desencriptaci\u00f3n del sistema de archivos ra\u00edz. <\/p>\n

Debido a los cambios significativos que se avecinan, se planea dividir la implementaci\u00f3n en varias etapas. En la primera etapa, el soporte para UKI se a\u00f1adir\u00e1 al cargador y comenzar\u00e1 la publicaci\u00f3n de una imagen opcional de UKI que estar\u00e1 centrada en el arranque m\u00e1quinas virtuales<\/a> con un conjunto limitado de componentes y controladores, as\u00ed como en las herramientas relacionadas con la instalaci\u00f3n y actualizaci\u00f3n de UKI. En la segunda y tercera etapas se planea eliminar la transmisi\u00f3n de configuraciones en la l\u00ednea de comandos del n\u00facleo y cesar el almacenamiento de claves en initrd.
