I was surprised I hadn't heard of this as a separate tool from systemd-nspawn. Then I realized why... the GitHub repo shows version 0.6 released in 2022, then version 1.0.0 last week, followed by a flurry of releases up to 1.8.0 yesterday.

So basically, it's been all Claude'd up extremely recently.

That said, the landing page, docs, and git README are much higher quality than I normally see out of LLM-generated projects, so at least the author knows how to reign in the needless verbosity and write for a technical audience. So I will give him credit for that at least.
