In der Version von Fedora Linux 40 wird die zweite Phase des \u00dcbergangs zu dem von Lennart Poettering vorgeschlagenen modernisierten Bootprozess realisiert. Die Unterschiede zum klassischen Bootvorgang bestehen darin, dass anstelle des bei der Installation des Kernel-Pakets lokal auf dem System erstellten Initrd-Images ein einheitliches Kernel-Image (UKI - Unified Kernel Image) verwendet wird, das in der Infrastruktur der Distribution generiert und durch die digitale Signatur der Distribution beglaubigt wird. Der Vorschlag wurde bisher vom FESCo-Komitee (Fedora Engineering Steering Committee), das f\u00fcr den technischen Teil der Entwicklung der Fedora-Distribution verantwortlich ist, nicht gepr\u00fcft. <\/p>\n

Das UKI-Image vereint in einer Datei den Boot-Handler f\u00fcr das Laden des Kerns aus UEFI (UEFI Boot Stub), das Linux-Kernel-Image und die im Arbeitsspeicher geladene Systemumgebung initrd. Bei der Ausf\u00fchrung des UKI-Images aus UEFI wird die M\u00f6glichkeit zur \u00dcberpr\u00fcfung der Integrit\u00e4t und Authentizit\u00e4t sowohl des Kerns als auch des Inhalts der initrd durch die digitale Signatur bereitgestellt, wobei die Authentizit\u00e4t entscheidend ist, da in dieser Umgebung die Schl\u00fcssel zur Entschl\u00fcsselung des Root-Filesystems extrahiert werden. <\/p>\n

Die erste Phase der Einf\u00fchrung von UKI wurde in Fedora Linux 38 durchgef\u00fchrt und f\u00fchrte zur Unterst\u00fctzung von UKI im Bootloader, zur Bereitstellung von Werkzeugen zur Installation und Aktualisierung von UKI sowie zur Erstellung eines experimentellen UKI-Images f\u00fcr das Booten. virtuelle Maschinen<\/a> mit einem eingeschr\u00e4nkten Satz von Komponenten und Treibern. <\/p>\n

In der zweiten Phase sollen die M\u00f6glichkeit der direkten Boot-UKI aus dem UEFI-Modul shim.efi ohne einen separaten Bootloader (grub, sd-boot) hinzugef\u00fcgt, die Verwendung von UKI auf Systemen mit der Architektur Aarch64 erm\u00f6glicht und eine UKI-Image-Variante f\u00fcr Cloud-Umgebungen und gesch\u00fctzte virtuelle Maschinen vorbereitet werden.
