La version Fedora 38 propose de mettre en \u0153uvre la premi\u00e8re \u00e9tape de la transition vers un processus de d\u00e9marrage modernis\u00e9, pr\u00e9c\u00e9demment sugg\u00e9r\u00e9 par Lennart Poettering, afin d'organiser un d\u00e9marrage v\u00e9rifi\u00e9 complet, englobant toutes les \u00e9tapes depuis le firmware jusqu'\u00e0 l'espace utilisateur, et pas seulement le noyau et le chargeur. La 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

Les composants n\u00e9cessaires \u00e0 la mise en \u0153uvre de l'id\u00e9e propos\u00e9e sont d\u00e9j\u00e0 int\u00e9gr\u00e9s dans systemd 252 et se r\u00e9sument \u00e0 l'utilisation, au lieu de l'image initrd, form\u00e9e sur le syst\u00e8me local lors de l'installation du paquet noyau, d'une image noyau unifi\u00e9e UKI (Unified Kernel Image), g\u00e9n\u00e9r\u00e9e dans l'infrastructure de la distribution et sign\u00e9e num\u00e9riquement par celle-ci. UKI regroupe dans un seul fichier le gestionnaire pour le d\u00e9marrage du noyau \u00e0 partir de l'UEFI (UEFI boot stub), l'image du noyau Linux et l'environnement syst\u00e8me initrd charg\u00e9 en m\u00e9moire. Lors de l'appel de l'image UKI depuis l'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 v\u00e9rification est importante car dans cet environnement s'effectue l'extraction des cl\u00e9s pour d\u00e9chiffrer le syst\u00e8me de fichiers racine. <\/p>\n

En raison des changements significatifs \u00e0 venir, la mise en \u0153uvre est pr\u00e9vue pour \u00eatre divis\u00e9e en plusieurs \u00e9tapes. Lors de la premi\u00e8re \u00e9tape, le support de l'UKI sera ajout\u00e9 au chargeur et la publication d'une image UKI optionnelle d\u00e9butera, centr\u00e9e sur le d\u00e9marrage machines virtuelles<\/a> avec un ensemble limit\u00e9 de composants et de pilotes, ainsi que des outils li\u00e9s \u00e0 l'installation et \u00e0 la mise \u00e0 jour de l'UKI. Les deuxi\u00e8me et troisi\u00e8me \u00e9tapes pr\u00e9voient d'abandonner le transfert des param\u00e8tres en ligne de commande du noyau et d'arr\u00eater de stocker les cl\u00e9s dans l'initrd.
