Systemd adds concrete primitives for authenticated and measured boot: sd-boot plus PID1 services calculate PCRs, write boot-phase values, and bind disk decryption keys and service secrets to the local machine and OS so secrets only unlock under specific measured states. systemd-measure precomputes PCR values and ukify embeds signed PCR policies into Unified Kernel Images. Credentials can be hierarchical and delivered from disk, TPM, or the bootloader; vmm_notify_socket passes readiness and exit status into guests; soft-reboot and fd-based APIs reduce race conditions.
