\u00cen versiunea Fedora 38, se propune implementarea primei etape a tranzi\u021biei c\u0103tre un proces de \u00eenc\u0103rcare modernizat, sugerat anterior de Lennart Poettering, pentru a organiza o \u00eenc\u0103rcare verificat\u0103 complet\u0103, care s\u0103 acopere toate etapele de la firmware la utilizator, nu doar nucleul \u0219i bootloaderul. Propunerea nu a fost \u00eenc\u0103 luat\u0103 \u00een considerare de comitetul FESCo (Fedora Engineering Steering Committee), responsabil pentru partea tehnic\u0103 a dezvolt\u0103rii distribu\u021biei Fedora. <\/p>\n
Componentele necesare realiz\u0103rii ideii propuse sunt deja integrate \u00een systemd 252 \u0219i se reduc la utilizarea unui nucleu unificat UKI (Unified Kernel Image) generat \u00een infrastructura distribu\u021biei, \u00een locul imaginii initrd formate pe sistemul local la instalarea pachetului cu nucleul, care este semnat digital de distribu\u021bie. UKI combin\u0103 \u00eentr-un singur fi\u0219ier un handler pentru \u00eenc\u0103rcarea nucleului din UEFI (UEFI boot stub), imaginea nucleului Linux \u0219i mediul ini\u021bial \u00eenc\u0103rcat \u00een memorie initrd. La apelarea imaginii UKI din UEFI, se ofer\u0103 posibilitatea verific\u0103rii integrit\u0103\u021bii \u0219i autenticit\u0103\u021bii prin semn\u0103tura digital\u0103 nu doar a nucleului, ci \u0219i a con\u021binutului initrd, verificarea autenticit\u0103\u021bii fiind important\u0103, deoarece \u00een acest mediu se extrag cheile pentru decriptarea sistemului de fi\u0219iere r\u0103d\u0103cin\u0103. <\/p>\n
Datorit\u0103 modific\u0103rilor semnificative anticipate, implementarea este planificat\u0103 s\u0103 fie \u00eemp\u0103r\u021bit\u0103 \u00een mai multe etape. \u00cen prima etap\u0103, suportul

set limitat de componente \u0219i drivere, precum \u0219i instrumentele asociate cu instalarea \u0219i actualizarea UKI. \u00cen etapele a doua \u0219i a treia, se preconizeaz\u0103 abandonarea
