The mascot it super cute lion too. How can a project do everything so right? I was browsing some popular python libraries and they just slapped on the first image they got out of ChatGPT. It's nice to see care in the craft.
On recent news, LionsOS, as of about a week ago (I got notified via their announcement maillist), includes a router/firewall scenario[0].
Do not miss Gernot Heiser's recent talk[1] at the seL4 Summit, where among other things he shows seL4 massively outperforming Linux in a web server scenario.
Genode is a framework that can run on many places and on higher level has its own abstractions. Lion OS is based on Microkit the framework developed by the seL4 people that will also be verified. So Lion OS/Microkit is basically the outgrowth of the original seL4 research.
I'm trying to picture in my mind a person who is a fan of Rust and somehow against an OS with a formally-verified kernel no matter the language. I'm not having much success.

What is the purpose of this OS ? Can it mint Bitcoin ? Can it do fluid dynamics simulation ? Can it act as an interface to a database ? Can it host a database ? Is it interactive ? What kind of interface it presents to the user ?
That’s a rather luridly practical view that’s entirely out of sync with academia and basic research that provides tangible benefits much further down the line.
Presumably named after Associate Professor John Lions[0], of A Commentary on the UNIX Operating System[1] fame.

It's developed by UNSW Sydney, whose mascot is a Lion. (Specifically, "Clancy the Lion"), so I am guessing it's probably that.
That's also where John Lions taught.
Not presumably, but explicitly. Both in documentation and presentations by seL4 they consistently make a point to mention so.

Mountain Lion is calling and wants its name back.
Very cool! I’m a huge fan of Genode, another OS that runs on SeL4. Does anyone here know how they compare?

Unequal
Oh no, it's written in C and not Rust. The blasphemy!

Rust, an immature language with fluidly evolving specification / reference implementation, is not suitable for high assurance nor formal verification.

Those are applications, not operating systems. With occasional exceptions, you can run any application on any operating system.
There is an example of interface in the docs: https://lionsos.org/docs/examples/kitty/
Yeah, Linus, what's the point?
