Kernel means "core". Kernel-mode-only kernel is a contradiction. If you don't have separate parts, you can't have a core.

So if you write core software for an architecture without privsep you must not call it a kernel?

[aortega]

I'm not talking about privsep, just different modules. I gonna answer you with another question:

Did MS-DOS had a kernel?

[nwg]

Yes. We all lose here today.

[aortega]

It depends. Being downvoted by people that believes a memcpy() is a kernel, is victory.
