Te tiszta hülye vagy, egyrészt kernel panic 2 éves aktív 24/7 desktopom mellett 1x nem fordult elő velem...
Hardver meghibásodástól pedig nem csoda ;)
Másik: monolitikus kernel egyáltalán nem elavult...MOST sem.
Hagy idézzek a linux kernel faq-ból:
"Why is the Linux kernel monolithic? Why don't we rewrite it as a microkernel?
* (REG) The short answer is why should we? The longer answer is that experience has shown that microkernels have poor performance compared to monolithic kernels. Microkernels have a fundamental design problem, where different components of the kernel cannot interact without passing a privilege barrier (which is expensive). Microkernel advocates claim this is a feature, as it increases modularity and protects one part of the kernel from another. Whether this is a feature or a mis-feature is in the eye of the beholder, but it is clear that there is a performance cost inherent in the microkernel design. This is a cost the Linux kernel developers (and apparently, the users) are unwilling to bear.
There are projects which have ported the Linux kernel to generic microkernels (such as Mach3), usually making Linux a "personality". There are also other projects to create microkernel-based Unix-like implementations. Here is a short list:
o MkLinux was funded by Apple, and runs Linux on PowerPC Macs. It is available at: http://www.mklinux.org/. An x86 version is also available. Note that there is now a native Linux kernel for the PowerPC which is much faster, and is actively maintained. MkLinux has become a historical footnote.
o The Hurd is a microkernel-based Unix, and is supposed to be the promised GNU kernel. It sits on top of Mach3. The Debian Project provides a full distribution for the Hurd.
o FIASCO is another project for creating MicroKernel LINUX. See http://os.inf.tu-dresden.de/fiasco/ for details.
There is a historical Usenet thread related to this subject, dating back from 1992, with posts from Linus, Andrew Tanenbaum, Roger Wolff, Theodore Y T'so, David Miller and others. Nice reading on a rainy afternoon. It's fascinating to see how some predictions (which seemed rather reasonable at the time) have proved wrong over the years (for example, that we would all be using RISC chips by 1998)."
"Linux is not a good computer science project. It is, however, good engineering. Understand the distinction, and you will understand why many widely acclaimed ideas in computer science are held with contempt in the Linux kernel developer community."
