  Linux Kernel 2.6: It's Worth More!
Many Linux kernel developers expect improved versions of their code to be continuously available to them, and a release using a BSD-style license would violate those developers' expectations.
The Linux kernel is clearly not an organic application; organic applications have a small software team developing software in a familiar, in-house environment, without significant communication overheads, and allow hard requirements to be negotiated away.
It could be argued that the Linux kernel is embedded, since it often operates in tight constraints; but in practice these constraints aren't very tight, and the kernel project can often negotiate requirements to a limited extent (e.g., providing only partial support for a particular peripheral or motherboard if key documentation is lacking).

  Linux kernel - Wikipedia, the free encyclopedia
The Linux kernel is a Unix-like operating system kernel that was begun by Linus Torvalds in 1991 and subsequently developed with the assistance of developers worldwide.
Currently, the Linux kernel is licensed under version 2 of the GPL, and there is some controversy over how easily it could be changed to use later GPL versions such as the upcoming version 3 (and whether this is desirable) [13].
The fact that Linux is not a microkernel was the topic of a famous flame war between Linus Torvalds and Andy Tanenbaum on comp.os.minix in 1992.

 Linux - Wikipedia, the free encyclopedia
Linux is now one of the most widely ported operating systems, running on a diverse range of systems from the hand-held ARM-based iPAQ to the mainframe IBM System z9.
Because all Linux distributions rely on libraries and tools from the GNU project, which predates the Linux kernel, Richard Stallman and the Free Software Foundation ask that the combined system be referred to as "GNU/Linux" or "a Linux-based GNU system".
Linux's Unix roots mean that while graphical configuration tools and control panels are available for many system settings and services, plain-text configuration files are still commonly used to configure the OS and may be exposed to users.

 Linux kernel patch from the Openwall Project

This said, the newest Linux kernel (2.6.5 as of this writing) has noticeable improvements for the typical desktop user as a result of the improved scheduling system in the new kernel.
Even for older kernels, rebuilding is often necessary for low memory situations, esoteric hardware, and in cases where every ounce of performance must be extracted.
The Linux kernel is often likened to the conductor in an orchestra.

 Conceptual Architecture of the Linux Kernel
The Linux kernel is useless in isolation; it participates as one part in a larger system that, as a whole, is useful.
At the highest level, the architectural style of the Linux kernel is closes to Garlan and Shaw's Data Abstraction style ([Garlan1994]); the kernel is composed of subsystems that maintain internal representation consistency by using a specific procedural interface.
The conceptual architecture of the Linux kernel has proved its success; essential factors for this success were the provision for the organization of developers, and the provision for system extensibility.

Linux is no longer maintained with the BitKeeper source code management system, but with GIT, a tool Linus wrote after BitKeeper was no longer available to all developers.
Some kernel developers, including Linus and Marcelo, have chosen to use GIT to manage their kernel source trees, but this does not mean you need to use GIT yourself to maintain your trees or submit patches.
