W wydaniu Fedora 38 zaproponowano wdro\u017cenie pierwszego etapu przej\u015bcia na zmodernizowany proces uruchamiania, wcze\u015bniej zaproponowany przez Lennarta Poetteringa, kt\u00f3ry ma zapewni\u0107 pe\u0142noprawne zweryfikowane uruchamianie obejmuj\u0105ce wszystkie etapy, od pami\u0119ci flash do przestrzeni u\u017cytkownika, a nie tylko j\u0105dra i loadera. Propozycja nie zosta\u0142a jeszcze rozpatrzona przez komitet FESCo (Fedora Engineering Steering Committee), kt\u00f3ry odpowiada za techniczne aspekty rozwoju dystrybucji Fedora. <\/p>\n

Elementy potrzebne do realizacji zaproponowanej idei zosta\u0142y ju\u017c zintegrowane w systemd 252 i sprowadzaj\u0105 si\u0119 do u\u017cycia zamiast obrazu initrd, formowanego na lokalnym systemie podczas instalacji pakietu z j\u0105drem, zunifikowanego obrazu j\u0105dra UKI (Unified Kernel Image), generowanego w infrastrukturze dystrybucji i zweryfikowanego cyfrowym podpisem dystrybucji. UKI \u0142\u0105czy w jednym pliku program \u0142aduj\u0105cy j\u0105dro z UEFI (UEFI boot stub), obraz j\u0105dra Linux oraz \u0142aduj\u0105ce si\u0119 do pami\u0119ci \u015brodowisko systemowe initrd. Przy wywo\u0142aniu obrazu UKI z UEFI istnieje mo\u017cliwo\u015b\u0107 weryfikacji integralno\u015bci i autentyczno\u015bci dzi\u0119ki cyfrowemu podpisowi, nie tylko j\u0105dra, ale i zawarto\u015bci initrd, weryfikacja kt\u00f3rej jest istotna, poniewa\u017c w tym \u015brodowisku odbywa si\u0119 wydobycie kluczy do deszyfrowania g\u0142\u00f3wnego systemu plik\u00f3w. <\/p>\n

Ze wzgl\u0119du na znacz\u0105ce nadchodz\u0105ce zmiany wdro\u017cenie planuje si\u0119 podzieli\u0107 na kilka etap\u00f3w. W pierwszej fazie wsparcie dla UKI zostanie dodane do bootloadera i rozpocznie si\u0119 publikacja opcjonalnego obrazu UKI, kt\u00f3ry skoncentruje si\u0119 na uruchamianiu maszyn wirtualnych<\/a> z ograniczon\u0105 liczb\u0105 komponent\u00f3w i sterownik\u00f3w, a tak\u017ce narz\u0119dzi zwi\u0105zanych z instalowaniem i aktualizowaniem UKI. W drugiej i trzeciej fazie planuje si\u0119 zrezygnowa\u0107 z przekazywania ustawie\u0144 w wierszu polece\u0144 j\u0105dra oraz zaprzesta\u0107 przechowywania kluczy w initrd.
