From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Great reason to push more code out of the kernel and into user land
Is it HURD'n' time?
I dunno, Stallman, it's been 30 years, you got something for us?
I'd just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/LInux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
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
Latest release was 9 years ago, not exactly what I'm looking for. 9front is probably closer to what I want than inferno.
Redox-OS?
Ah shit MIT license
Is that bad?
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
Interesting, but why implement yet another windowing system?
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?
That bit on their FAQ is amusing.
eBPF is looking great.
So what you are saying is “mach was right”?
Everybody knows it was. Even Linus said a microkernel architecture was better. He just wanted something working “now” for his hobby project, and microkernel research was still ongoing then.
