In this talk I'd like to discuss the "systemd Credentials" concept, which was introduced back in systemd v250 and became a powerful mechanism for parameterizing Linux systems and services.
These credentials can be passed into systems and services, can be authenticated and encrypted by TPMs. They can be acquired from SMBIOS, via Cloud IMDS services, the UEFI System Partition, or local file systems and IPC. They have a well-defined life-cycle, and can be securely inherited down the process, container and VM hierarchy.
We'll compare them with other ways to parameterize systems and services, such as the kernel command line or environment blocks, and explain why systemd's credentials are often the much better approach.
