Nella versione di Fedora Linux 40 si prevede di realizzare la seconda fase della transizione verso un processo di avvio modernizzato, proposto da Lennart Poettering. Le differenze rispetto all'avvio classico riguardano l'uso, al posto dell'immagine initrd, di un'immagine kernel unificata UKI (Unified Kernel Image), generata nell'infrastruttura della distribuzione e firmata digitalmente dalla distribuzione. La proposta non \u00e8 ancora stata esaminata dal comitato FESCo (Fedora Engineering Steering Committee), responsabile della parte tecnica dello sviluppo della distribuzione Fedora. <\/p>\n

L'immagine UKI riunisce in un unico file il gestore per l'avvio del kernel da UEFI (UEFI boot stub), l'immagine del kernel Linux e l'ambiente di sistema initrd caricato in memoria. Quando viene richiamata l'immagine UKI da UEFI, si offre la possibilit\u00e0 di controllare l'integrit\u00e0 e l'autenticit\u00e0 tramite la firma digitale non solo del kernel, ma anche del contenuto di initrd, il cui controllo \u00e8 importante poich\u00e9 in questo ambiente avviene l'estrazione delle chiavi per decriptare il filesystem radice. <\/p>\n

La prima fase dell'implementazione di UKI \u00e8 stata completata in Fedora Linux 38 e ha portato all'aggiunta del supporto UKI nel boot loader, all'implementazione di strumenti per l'installazione e l'aggiornamento di UKI, e alla creazione di un'immagine UKI sperimentale per l'avvio. macchine virtuali<\/a> con un insieme limitato di componenti e driver. <\/p>\n

Nella seconda fase si prevede di aggiungere la possibilit\u00e0 di avviare direttamente UKI dal modulo UEFI shim.efi senza l'ausilio di un boot loader separato (grub, sd-boot), di implementare la possibilit\u00e0 di utilizzare UKI su sistemi con architettura Aarch64 e di preparare una variante dell'immagine UKI per ambienti cloud e macchine virtuali sicure.
