Which words do you think are buzzwords in the description? What I think of by buzzwords are things like “Blockchain”, “Machine Learning” etc. which are generic topics used to build hype whilst not really explaining anything.

In this case however, the words are all fairly precise and accurate (at least from my basic understanding of systemd). They might not be words used in everyday conversation, but they don’t need to be unless the document is targeted as introductory material (which I don’t think is the case).

That’s not to say this is the only way to explain it, but it is a very concise way, which I at appreciate.
