Kernel programming is the hardest kind. Not anything for a beginner, I think!

No. You can't relicence someone else's code.

[2]

Why v2? Minix 2.0 is long long obsolete.

https://minix1.woodhull.com/FAQ.html

Minix 2 only ran on x86 and Motorola 68000. No Arm version, as far as I can see.

Minix 3 is the interesting version. It is the microkernel.

However, even so:

That makes no sense.

Ubuntu is a Linux. A complex, full-function Linux at that.

Secondly, it is derived from Debian.

Debian has had versions with other kernels before but it's a hard
target and all but 1 are discontinued

https://www.debian.org/ports/kfreebsd-gnu/ <- dead

https://www.debian.org/ports/netbsd/ <- dead

 https://www.debian.org/ports/hurd/ <- sort of alive

More appropriate would be to try to learn by building a simpler Unix.
There are many.

Version 6 Unix:

Version 7 Unix:

Minix 3 does support Arm:

https://wiki.minix3.org/doku.php?id=developersguide:minixonarm

But it's rough -- better to start on x86.

Do you mean "OR a Xeon"?

No need to focus on what model of Xeon. Any x86 chip will do.

What? Why?

Then again, why?

So don't.

Those are processors, not kernels.

Don't?

Just learn to use an x86 hypervisor and use that?

Virtualbox is the easiest.

But... listen.

Microkernels are a largely discarded idea now. The communications
(IPC, inter-process communications) between modules are too hard to do
with good performance.

Plan 9 showed that using the filesystem is much simpler and more
efficient than IPC.

https://9p.io/plan9/

A fork called 9front is still alive and active. There was a new
release last week.

http://9front.org/releases/2023/06/25/0/

Learn that. Learn C and kernel coding on Plan 9.

Forget Ubuntu. It is approximately 1000x bigger and more complicated.

> i hope i interest some people,

I am sorry to have to be so direct, but you seem very confused, and
you want to start learning how to build a brick wall by building a new
Empire State Building as your first effort.

IMHO this is foolish and misguided. Start small. Start as small as you can!

In fact, maybe a better starting place would be Fuzix, an even smaller OS.
