Linux BeOS is interesting 
but does it use Haiku and Linux things?
Why would anyone want that?

I think cuz it has haiku hpkg/recipe and BeOS software, along with Linux thing
This particular one is not just a skin on top of some X11 window manager. In fact it has neither wayland nor X11 so the idea would be to recompile BeOS/Haiku apps to run on it.
I don’t see the point, but who am I to judge someone else’s hobby?

For a human-centric operating system, that 0.3.0 announcement post does not read as very human-written. Awful lot of “it’s not x, it’s y” in there.

To run native BeOS / Haiku apps on a kernel with better hardware support than Haiku can currently offer?

For me, to design and test Interface Kit hardware acceleration and multiple screens support over already existing solid foundation (Linux DRM/KMS). It is easier to implements parts independently then wait until proper GPU drivers will be implemented in Haiku.

Note is seems ABI-incompatible with Haiku, so HaikuPorts software will not work without recompilation. Also it seems unable to run X11/Wayland-based Linux GUI software.

I don’t think that would be possible since BeOS source code is only available haiku so they would need to get a hold of that and for haiku format they would a compatibility layer or would need to recompile everything again
There have been so many “Haiku with Linux kernel” projects over the years and none managed to stay around for a long time.
I don’t really see a point in such a project,or any good reason to use it.
What’s so bad about Haikus kernel that everyone wants to replace it?
For me it works really well in most cases,and when it doesn’t,it can be fixed directly because it’s a part of Haiku itself.
Having everything it needs for a fully usable operating system in one place is one of the biggest advantages of Haiku in my opinion.

The benefits would be things like driver support and stability.

I’ve tried it in a QEMU vm. As the version number suggests it is in pretty early stage. Tracker doesn’t seem to be working yet. Still, an interesting project. Will check from time to time how it progresses.

If anyone has been following the posts on The AmigaOS Refugees thread, the Ax runtime from the Aros Zune GUI is far lighter by itself than what either X11 or Wayland by themselves, let-alone a full desktop. This has potential to be better yet.
Just imagine being able to run Haiku’s XLibE on top of this and immediately render the real thing obsolete overnight. If the overhead is negligible, getting support to Haiku’s libraries become a no-brainer, even on the Linux kernel.

Xlibe is a great project, but it’s not exactly a drop-in replacement for X11.
If it proves to be maintainable to a greater extent than the original, it becomes the basis for the rewrite that Linux users have wanted for over a decade.
The more options, the merrier.
I work with Ubuntu 24.04 Server as an embedded base for certain devices with 3-4 displays, 2 with touch input. Vulkan. The 3rd party embedded drivers are Linux. I dont see Haiku filling this role for at least a decade. Linux has thousands of optimisations that are a decade away from Haiku
If projects like these were mature, then great, we could have a Haiku userland during dev which in my opinion is more pleasant than the Linux based experience. AppServer has minimal testing with multimonitor setups, projects like these can prototype various solutions, and when the real AppServer is ready, it gains an “implementation for comparison”.
I do love the Haiku philosophy, and a true Haiku kernel in a symbiotic relationship with Haiku Appserver and userland will always integrate better than the Frankenstein mess that is Linux.
Projects like V\OS are a stepping stone. The devs can enjoy their pet projects. The experience will cross polinate.
Who knows, this may bring more Linux devs to Haiku as well. Look at React OS (the WinNT open source clone). It had some community excitement until Wine/Proton extinguished that fire. Why bother with ReactOS since binary compatible Windows apps are also available on Linux.
There will be a day when you can run Wine on Haiku, and Gtk/Kde apps on Haiku, and maybe even binary Linux apps on Haiku. Any app on any system. The differentiator will be where the most pleasant experience is. Haiku wins that race eventually. Its a journey.
As I said, the more the merrier.

That part at least is already possible

This is an inversion of reality. ReactOS was considered a joke for most of its history. Now there are people doing 10 hour “let’s plays” with seemingly perfect 3D acceleration, and lots of people are very excited and saying they want to replace Windows with ReactOS.
