\u00cen versiunea Fedora Linux 40 se preconizeaz\u0103 implementarea celei de-a doua etape a tranzi\u021biei c\u0103tre un proces de \u00eenc\u0103rcare modernizat, propus de Lennart Poettering. Diferen\u021bele fa\u021b\u0103 de \u00eenc\u0103rcarea clasic\u0103 se reduc la utilizarea, \u00een locul imaginii initrd, a unei imagini unificate a nucleului UKI (Unified Kernel Image), generat\u0103 \u00een infrastructura distribu\u021biei \u0219i semnat\u0103 digital de distribu\u021bie. Propunerea nu a fost \u00eenc\u0103 analizat\u0103 de comitetul FESCo (Fedora Engineering Steering Committee), care se ocup\u0103 de partea tehnic\u0103 a dezvolt\u0103rii distribu\u021biei Fedora. <\/p>\n

Imaginea UKI reune\u0219te \u00eentr-un singur fi\u0219ier un handler pentru \u00eenc\u0103rcarea nucleului din UEFI (UEFI boot stub), imaginea nucleului Linux \u0219i mediul de sistem initrd care se \u00eencarc\u0103 \u00een memorie. Atunci c\u00e2nd imaginea UKI este apelat\u0103 din UEFI, exist\u0103 posibilitatea de a verifica integritatea \u0219i autenticitatea prin semn\u0103tura digital\u0103 nu doar a nucleului, ci \u0219i a con\u021binutului initrd, verificarea autenticit\u0103\u021bii c\u0103ruia este important\u0103 deoarece \u00een acest mediu se execut\u0103 extragerea cheilor pentru decriptarea sistemului de fi\u0219iere r\u0103d\u0103cin\u0103. <\/p>\n

Prima etap\u0103 de implementare a UKI a fost realizat\u0103 \u00een Fedora Linux 38 \u0219i a dus la ad\u0103ugarea suportului UKI \u00een \u00eenc\u0103rc\u0103tor, realizarea instrumentarului pentru instalarea \u0219i actualizarea UKI, precum \u0219i generarea unei imagini experimentale UKI pentru \u00eenc\u0103rcare. ma\u0219ini virtuale<\/a> cu un set limitat de componente \u0219i drivere. <\/p>\n

\u00cen a doua etap\u0103, se inten\u021bioneaz\u0103 ad\u0103ugarea posibilit\u0103\u021bii de \u00eenc\u0103rcare direct\u0103 a UKI din modulul UEFI shim.efi f\u0103r\u0103 a implica un \u00eenc\u0103rc\u0103tor separat (grub, sd-boot), implementarea posibilit\u0103\u021bii de utilizare a UKI pe sisteme cu arhitectur\u0103 Aarch64 \u0219i preg\u0103tirea unei variante a imaginii UKI pentru medii cloud \u0219i ma\u0219ini virtuale securizate.
