Systemd is gaining new functionality outside traditional service management. The talk will cover some of those areas.
An area of significant development is authenticated and measured boot, both in the boot loader (sd-boot) and in the running system (PID1, new services). We are building infrastructure to bind decryption of disks and service secrets to the local machine and operating system. The measurements of system state are now much more comprehensive and can be used to build a nuanced policy for access to secrets and remote attestation.
A related area of improvement is the support for Unified Kernel Images. https://fedoraproject.org/wiki/Changes/Unified_Kernel_Support_Phase_1 was accepted for Fedora 38. Systemd gained new tools to pre-calculate PCR values, sign policies and bind secrets (before booting into a given kernel), and build UKIs with those policies embedded.
I'll describe what is already implemented and what we think will be possible in the future.
