DDIs are supposed to carry dm-verity authentication information, i.e. every single access to them is typically cryptographically protected, and linked back to a set of signing keys maintained by the system (ideally in the kernel keyring). systemd uses DDIs for the system itself, for systemd-nspawn containers, for systemd portable services, for systemd-sysext system extensions, for systemd-confext configuration extensions and more.
