Redox would probably be the best option. The BSDs, it would probably be an uphill fight to. I believe it's been floated, but no movement on incorporating Rust in the BSD kernels. So I they would have to start form scratch. The benefit of Linux in this case is, the Asahi team isn't single handily doing all the Rust in the Linux kernel, right. There are other Rust people and Rust for Linux was already getting somewhat bootstrapped before the Asahi project. With the BSDs, you would have to start with bootstrapping Rust in the kernels and build systems.

FreeBSD may be open to it? It's been awhile, and I haven't kept up to date on it for a year or two. But once again, I think you'd have to start from scratch. So everything for R4L that was built before Asahi Linux needs to be done on the FreeBSD side.

NetBSD is probably a no go. NetBSD supports architectures that Rust (due to LLVM) can't support. Which means it is most likely a no go for NetBSD, NetBSD's schtick is that it can run on anything and they will fully do everything in their power to make sure NetBSD can run on any hardware and be maintained. Hardware portability matters for them.

The attitude I've seen from OpenBSD devs is, the answer is to 'git gud' at C and, not replace C code with Rust. Or in other words, they have no interest in Rust in the OpenBSD kernel.

I don't really know where DragonFlyBSD falls in this. Its the BSD I know the least about.
