Nella release di Fedora 38 \u00e8 proposta l'implementazione della prima fase di transizione verso un processo di avvio modernizzato, precedentemente suggerito da Lennart Poettering, per organizzare un avvio completamente verificato che copra tutte le fasi, dal firmware allo spazio utente, e non solo il kernel e il bootloader. 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
I componenti per implementare l'idea proposta sono gi\u00e0 integrati in systemd 252 e consistono nell'utilizzare, anzich\u00e9 un'immagine initrd formata localmente durante l'installazione del pacchetto del kernel, un'immagine del kernel unificata UKI (Unified Kernel Image), generata nell'infrastruttura della distribuzione e firmata digitalmente dalla distribuzione. UKI unisce in un unico file un 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 si chiama l'immagine UKI da UEFI, viene fornita la possibilit\u00e0 di verificare l'integrit\u00e0 e l'affidabilit\u00e0 attraverso la firma digitale, non solo del kernel ma anche del contenuto di initrd, la cui verifica \u00e8 importante poich\u00e9 in questo ambiente vengono estratti le chiavi per decrittografare il filesystem radice. <\/p>\n
A causa dei notevoli cambiamenti previsti, l'implementazione \u00e8 pianificata per essere suddivisa in diverse fasi. Nella prima fase, il supporto per UKI sar\u00e0 aggiunto al bootloader e inizier\u00e0 la pubblicazione di un'immagine UKI opzionale, che sar\u00e0 focalizzata sull'avvio macchine virtuali<\/a> con un set limitato di componenti e driver, oltre agli strumenti associati all'installazione e all'aggiornamento di UKI. Nelle seconde e terze fasi \u00e8 prevista l'abbandono della trasmissione delle impostazioni nella riga di comando del kernel e la cessazione della memorizzazione delle chiavi in initrd. \u0412
