Under no circumstances, it’s a microkernel for embedded systems. It’s like asking under what scenarios would you want to drive an ATV through New York. Technically possible, but that’s just not what it was made to do.

In practice, Linux is everywhere now, often in places where it should not be. Linux is truck/SUV of computer world if I can extend your analogy. It doesn't belong to center of big city, but it is here.

My conversations with people who have implemented Linux where it shouldn’t have been have essentially boiled down to it being easier to hire Linux developers than embedded systems developers

I work in the industry that builds and integrates most of that stuff. We don't use that term. It's marketing woo which is why the other commenter has probably never heard it.

> It's marketing woo Nah, it's a term used in academia.

IIRC it started with government institutions and think tanks, and quickly adopted by academia.

I work in defense and it is extremely common. That doesn’t mean it isn’t marketing fluff, but I was genuinely surprised they didn’t know and/or thought they were being snarky.

Yes, it is "good enough" and familiar to everybody in industry. I understand that. But it doesn't mean we don't need to try harder.

Tangentially related

The LionsOS name is a direct callback to the John Lions Lions' Commentary on UNIX 6th Edition, an Australian computer scientist and somewhat nomadic Professor.

Trustworthy, as seen in the post link, also hails from New South Wales.

What, pray tell, are “cyberphysical” systems?

Also involved with some of these industries, no academia/government though, so my perspective may be incomplete. Anecdotally I can’t remember hearing this term used.

After reading the Wikipedia page and a couple corporate pages about cyberphysical, I think it looks like it’s more about rebranding existing systems that contain interacting heterogenous elements with different RT needs, rather than introducing fundamentally new systems methodologies or technologies. It kinda reminds me of Agile, where a shift in mindset and terminology was hyped way more than any legitimate improvement in the underlying systems being built, and engineering “Agile products” became so important for some businesses.

Yeah, you pick up .gov buzzwords pretty quickly if you want your grants approved.
