Hi, I've confirmed the commit "Mark the sheepdog driver as unsupported" [1]. Sorry for CI failure. The problem will be fixed by Sheepdog team soon. I have an opinion about license. AFAIU, except CI failure, the reason why the Sheepdog driver was marked is that "dog", Sheepdog admin command line, is considered an external *library* licensed under GPLv2. However, "dog" is *executable*, not library. The Sheepdog driver communicates with "dog" in inter-process manner. So I think the driver does not violate the licensing requirements [2]. The paragraph including "external libraries" does not seem to be applied.
