Dans la version de Fedora Linux 40, la deuxi\u00e8me phase de la transition vers un processus de d\u00e9marrage modernis\u00e9 propos\u00e9 par Lennart Pottinger est pr\u00e9vue. Les diff\u00e9rences par rapport au d\u00e9marrage classique r\u00e9sident dans l'utilisation d'une image de noyau unifi\u00e9e (UKI - Unified Kernel Image) g\u00e9n\u00e9r\u00e9e dans l'infrastructure de distribution, certifi\u00e9e par une signature num\u00e9rique, au lieu de l'image initrd form\u00e9e sur le syst\u00e8me local lors de l'installation du paquet avec le noyau. Cette proposition n'a pas encore \u00e9t\u00e9 examin\u00e9e par le comit\u00e9 FESCo (Fedora Engineering Steering Committee), responsable de la partie technique du d\u00e9veloppement de la distribution Fedora. <\/p>\n

L'image UKI combine en un seul fichier le gestionnaire de d\u00e9marrage pour le chargement du noyau depuis UEFI (UEFI boot stub), l'image du noyau Linux et l'environnement d'initialisation initrd charg\u00e9 en m\u00e9moire. Lors de l'appel de l'image UKI depuis UEFI, il est possible de v\u00e9rifier l'int\u00e9grit\u00e9 et l'authenticit\u00e9 par la signature num\u00e9rique non seulement du noyau, mais aussi du contenu de l'initrd, dont la validation est importante, car dans cet environnement, les cl\u00e9s pour d\u00e9chiffrer le syst\u00e8me de fichiers racine sont extraites. <\/p>\n

La premi\u00e8re phase de l'impl\u00e9mentation de l'UKI a \u00e9t\u00e9 r\u00e9alis\u00e9e dans Fedora Linux 38 et a conduit \u00e0 l'ajout de la prise en charge de l'UKI dans le chargeur de d\u00e9marrage, \u00e0 la mise en \u0153uvre des outils pour l'installation et la mise \u00e0 jour de l'UKI, ainsi qu'\u00e0 la cr\u00e9ation d'une image exp\u00e9rimentale de l'UKI pour le d\u00e9marrage. machines virtuelles<\/a> avec un ensemble limit\u00e9 de composants et de pilotes. <\/p>\n

Lors de la deuxi\u00e8me phase, il est pr\u00e9vu d'ajouter la possibilit\u00e9 de d\u00e9marrer directement l'UKI \u00e0 partir du module UEFI shim.efi sans recourir \u00e0 un chargeur de d\u00e9marrage s\u00e9par\u00e9 (grub, sd-boot), de mettre en \u0153uvre la possibilit\u00e9 d'utiliser l'UKI sur des syst\u00e8mes avec architecture Aarch64 et de pr\u00e9parer une version de l'image UKI pour les environnements cloud et les machines virtuelles s\u00e9curis\u00e9es.
