Gentoo Linux – Introduction

Gentoo Linux ( ) is a computer operating system built on top of the Linux kernel and based on the Portage package management system. It is distributed as free and open source software, but includes some proprietary software packages. Unlike a conventional software distribution, the user compiles the source code locally according to their chosen [...]

Distributed lock manager – Linux clustering

Both Red Hat and Oracle have developed clustering software for Linux. OCFS2, the Oracle Cluster File System was added to the official Linux kernel with version 2.6.16, in January 2006. The alpha-quality code warning on OCFS2 was removed in 2.6.19. Red Hat’s cluster software, including their DLM and Global File System was officially added to [...]

GNU Project – Introduction

GNU Project is a free software, mass collaboration project, announced on September 27, 1983, by Richard Stallman at MIT. It initiated the GNU operating system, software development for which began in January 1984. The founding goal of the project was, in the words of its initial announcement, to develop “”a sufficient body of free software [...]

Physical Address Extension – Operating-system support

FreeBSD FreeBSD supports PAE in the 4.x series starting with 4.9, in the 5.x series starting with 5.1, and in all 6.x and later releases. Support requires the kernel PAE configuration-option. Loadable kernel modules can only be loaded into a kernel with PAE enabled if the modules were built with PAE enabled; the binary modules [...]

Linux distribution – Introduction

Linux distribution (also called GNU/Linux distribution by some vendors and users) is a member of the family of Unix-like software distributions built on top of the Linux kernel. Such distributions (often called ”distros” for short) consist of a large collection of software applications such as word processors, spreadsheets, media players and database applications. The operating [...]

Fedora (operating system) – Introduction

Fedora is an RPM-based, general purpose operating system built on top of the Linux kernel, developed by the community-supported Fedora Project and sponsored by Red Hat. The Fedora Project’s mission is to lead the advancement of free and open source software and content as a collaborative community. One of Fedora’s main objectives is not only [...]

System call – Examples and tools

On Unix, Unix-like and other POSIX-compatible operating systems, popular system calls are open, read, write, close, wait, exec, fork, exit, and kill. Many of today’s operating systems have hundreds of system calls. For example, Linux has 319 different calls, and FreeBSD has almost 500. Tools such as strace and truss allow a process to execute [...]

Klik (packaging method) – Technology

klik does not “install” software in the traditional sense (i.e., it does not put files all over the place in the system). It uses one .cmg file per application. Each one is self-contained: it includes all libraries the application depends on and that are not part of the base system. In this regard, it is [...]

CRUX – Installation

CRUX, unlike other GNU/Linux distributions, doesn’t include a GUI installation program. Instead, the user boots the kernel stored on either a CD or diskette; partitions the hard disk drive(s) to which the operating system will be installed (using a program such as fdisk or cfdisk); creates the appropriate file systems on the various partitions; mounts [...]

LILO (boot loader) – Introduction

LILO does not depend on a specific file system, and can boot an operating system (e.g., Linux kernel images) from floppy disks and hard disks. One of up to sixteen different images can be selected at boot time. Various parameters, such as the root device, can be set independently for each kernel. LILO can be [...]

Richard Stallman – GNU project

Stallman announced the plan for the GNU operating system in September 1983 on several ARPANET mailing lists and USENET. In 1985, Stallman published the GNU Manifesto, which outlined his motivation for creating a free operating system called GNU, which would be compatible with Unix. The name GNU is a recursive acronym for “GNU’s Not Unix.” [...]

MINIX – Introduction

MINIX is a Unix-like computer operating system based on a microkernel architecture created by Andrew S. Tanenbaum for educational purposes; MINIX also inspired the creation of the Linux kernel. MINIX (from “mini-Unix”) was first released in 1987, with its complete source code made available to universities for study in courses and research. It has been [...]

Linux – Design

A Linux-based system is a modular Unix-like operating system. It derives much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, and peripheral and file system access. Device drivers are either integrated directly with the [...]

MkLinux – Introduction

MkLinux is an open source computer operating system started by the OSF Research Institute and Apple Computer in February 1996 to port Linux to the PowerPC platform, and Macintosh computers. The effort was spearheaded by Brett Halle at Apple and development split between Michael Burg at Apple in Cupertino, California, (device drivers and distribution), and [...]
