And this is different from how things are now in what way? They've already got enough reasons to laugh at the major F/OSS operating systems without even looking at the GUI side of things. Let's try Linux: kernel modules, no stable API or ABI, subsystems being redone and overlayed atop one another... should I go on? "
That's the Kernel no stable API nonsense?
http://www.kernel.org/pub/linux/kernel/people/gregkh/misc/2.6/stabl... [/q]
This is a key block of text.
This is being written to try to explain why Linux does not have a binary kernel interface, nor does it have a stable kernel interface. Please realize that this article describes the _in kernel_ interfaces, not the kernel to userspace interfaces. The kernel to userspace interface is the one that application programs use, the syscall interface. That interface is _very_ stable over time, and will not break. I have old programs that were built on a pre 0.9something kernel that still works just fine on the latest 2.6 kernel release. This interface is the one that users and application programmers can count on being stable.
Notice this is very clear to point out kernel to userspace has been stable from 0.9 Linux something. So there is a stable ABI/API. Of course everyone raising the arguement forgets the existance of these.

and of course Buse.
There are all ways to create drivers using the stable kernel to user-space interface. Now the question becomes why do you need a Kernel ABI in the first place other than the Userspace one?
