En la versi\u00f3n de Fedora Linux 40, se planea implementar la segunda fase de la transici\u00f3n al proceso de arranque mejorado propuesto por Lennart Poettering. Las diferencias con el arranque cl\u00e1sico radican en el uso de una imagen de n\u00facleo unificada, UKI (Unified Kernel Image), generada en la infraestructura de la distribuci\u00f3n y firmada digitalmente por la distribuci\u00f3n, en lugar de la imagen initrd, que se forma localmente al instalar el paquete del n\u00facleo. La propuesta a\u00fan no ha sido considerada por el comit\u00e9 FESCo (Fedora Engineering Steering Committee), encargado de la parte t\u00e9cnica del desarrollo de la distribuci\u00f3n Fedora. <\/p>\n

La imagen UKI combina en un solo archivo un manejador para cargar el n\u00facleo desde UEFI (UEFI boot stub), la imagen del n\u00facleo Linux y el entorno del sistema initrd que se carga en memoria. Cuando se invoca la imagen UKI desde UEFI, se proporciona la capacidad de verificar la integridad y autenticidad a trav\u00e9s de la firma digital, no solo del n\u00facleo, sino tambi\u00e9n del contenido de initrd, cuya verificaci\u00f3n es crucial, ya que en este entorno se extraen las claves para descifrar el sistema de archivos ra\u00edz. <\/p>\n

La primera fase de implementaci\u00f3n de UKI se llev\u00f3 a cabo en Fedora Linux 38 y result\u00f3 en la adici\u00f3n de soporte para UKI en el gestor de arranque, la implementaci\u00f3n de herramientas para instalar y actualizar UKI, as\u00ed como la generaci\u00f3n de una imagen experimental de UKI para arranque. m\u00e1quinas virtuales<\/a> con un conjunto limitado de componentes y controladores. <\/p>\n

En la segunda fase, se pretende a\u00f1adir la capacidad de arranque directo de UKI desde el m\u00f3dulo UEFI shim.efi sin la necesidad de un gestor de arranque separado (grub, sd-boot), implementar la posibilidad de usar UKI en sistemas con arquitectura Aarch64 y preparar una variante de imagen UKI para entornos en la nube y m\u00e1quinas virtuales protegidas.
