There are even several ways to edit the kernel configuration before building the kernel. Customizable kernel: Linux is probably the most customizable Unix-like kernel.

#WIKIPEDIA RED HAT ENTERPRISE LINUX INSTALL#

In general, the Linux distro vendors take care of making updates install correctly.

#WIKIPEDIA RED HAT ENTERPRISE LINUX UPDATE#

Both kernel and userland maintain extra compatibility so that one can update only the kernel, or only some userland package like the C library.

Linus Torvalds and his team can worry about the kernel (and userland programs which query and configure the kernel) and let other teams develop the userland system separately.

With most other Unix-like systems, the kernel is maintained at least with the basic set of utilities, which would include the shell, shell utilities, C compiler, C library, system configuration utilities, and system boot scripts.

Separate development: The Linux kernel is developed and maintained separately from userland.

Every Linux vendor provides Linux source code. If you modify Linux or another package using this license, you can redistribute your modified version, but you must use the same license, which means you must provide source code. Many of the userland packages also use this license.

Mascot: The official mascot of Linux is Tux, the Linux penguin.

Each distro decides which packages to provide. There are also non-free packages without source code, or requiring one to buy licenses.

Packages: A complete GNU/Linux operating system uses many free software (open source) packages from the BSD, X11, GNU, and other projects.Wikipedia has a list of Linux distributions.A Neutral Look at Operating Systems has a comparison of Linux systems.Live CDs or DVDs allow users to boot from a disc and run Linux using a RAM disk rather than a hard disk. One can also inexpensively purchase a Linux distro as a retail package. One can download them as a raw disc image in ISO format and burn it. Typically, distributions are in CD or DVD form.Some distributions have different target audiences: these might be home users, enterprise users, free software supporters, hobbyists, or users of certain applications. There is much variation between distributions concerning the available packages, the installation procedure, the preferred desktop environment, and even the Linux kernel configuration.A Linux distribution (or 'distro' for short) is a bundle of the Linux kernel and applications and a suite of programs for installing and maintaining a Linux system. Distributions: The Linux system that you actually obtain, install, and run, is one of the many available Linux distributions.In Guide to UNIX, "tux" has an account on the example machines. Tux is now also the hero of some Linux games. After Linus Torvalds suggested a penguin, Larry Ewing used The GIMP to draw this popular image of Tux, the Linux mascot.
