Earlier quoted context omitted.
Extremely outdated. In the 15 versions since then, systemd has evolved quite tremendously with too many things to list succinctly.
Ok, I'll bite. What does systemd itself link to now?

They've replaced libattr with librt, otherwise the linked libraries are the same. Also, the package dependencies are the same.What's this about being out of date? Systemd changes very fast, but no additional libraries are linked to and one was changed, and no additional package dependencies required.
I'll have a look at interface changes next.
