Docker's never been quite as portable as imagined because of this. I wonder if this will make people rethink it as a model for containerization.

Interestingly, FreeBSD has native Docker support because it has a Linux compatibility layer that adds/maps/implements(?) Linux system calls so it FreeBSD can run Linux binaries. Looks like FreeBSD Docker support is also broken right now.

The annoying thing is that it should be that portable - docker is modular enough that you should be able to replace containerd/runc with a jail-based version and everything just works, and the OCI image format outright talks about features to make the system OS-agnostic. It's just that nobody's bothered to actually implement it:(
