What is the state of the art for running NetBSD (and other *BSD) in CI such as GitHub actions? Edit: to add a bit more detail, I maintain a cross platform tool [1] on GitHub and require a way to build and test it in CI for several platform not natively supported by GitHub. Currently I use cargo-cross [2] to build it from a Linux OS but this doesn’t work for running the tests. One option I’m aware of is running a qemu VM on Linux, which is the approach taken by postgres [3]. Another option is using an external CI provider such as Cirrus who claim to have native support [4] for various *BSD.
