L4. HURD never panned out, and L4 is where the microkernel research settled: Memory protection, scheduling, IPC in the kernel the rest outside and there’s also important insights as to the APIs to do that with. In particular the IPC mechanism is opaque, the kernel doesn’t actually read the messages which was the main innovation over Mach.
Literally billions of devices run OKL4, seL4 systems are also in mass production. Think broadband processors, automotive, that kind of stuff.
The kernel being watertight doesn’t mean that your system is, though, you generally don’t need kernel privileges to exfiltrate any data or generally mess around, root suffices.
If you want to see this happening – I guess port AMDGPU to an L4?
It means anyone including microsoft or apple can use the code contribution or take the entire softwarw and make some modifications and sell it proprietary. Any optimisations or features made by community can be proprietarised
Great reason to push more code out of the kernel and into user land
eBPF is looking great.
Is it HURD’n’ time?

I think we should just resurrect Plan 9 instead.
Plan 9 is also monolithic, according to wikipedia. For BSD it depends.
I mean, you’re right but I still want to see a modernized plan 9, I just think it would be neat.
that would be Inferno
I dunno, Stallman, it’s been 30 years, you got something for us?
Redox-OS?
Ah shit MIT license
Is that bad?

So what you are saying is “mach was right”?
