Runit
runit is an init and service management scheme for Unix-like operating systems that initializes, supervises, and ends processes throughout the operating system. Runit is a reimplementation of the daemontools process supervision toolkit that runs on many Linux-based operating systems, as well as BSD, and Solaris operating systems. Runit features parallelization of the start up of system services, which can speed up the boot time of the operating system. When running as an init daemon, Runit is the direct or indirect ancestor of all other processes. It is the first process started during booting, and continues running until the system is shut down. It is often used with other init systems as a separate service manager. In the service manager role, it can be used by unprivileged users to orchestrate personal services, as well as by root to manage services not otherwise managed by the init system currently in use. Design Runit focuses on being a small, modular, and portable codeb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Void Linux
Void Linux is an independent Linux distribution that uses the X Binary Package System (XBPS) package manager, which was designed and implemented from scratch, and the runit init system. Excluding binary blobs, binary kernel blobs, a base install is composed entirely of free software (but users can access an official non-free repository to install proprietary software as well). History Void Linux was created in 2008 by Juan Romero Pardines, a former developer of NetBSD, to have a test-bed for the XBPS package manager. The ability to natively build packages from source using xbps-src is likely inspired by pkgsrc and Ports collection, other BSD ports collections. In May 2018, the project was moved to a new website and code repository by the core team after the project leader had not been heard from for several months. As of April 2022, Void is the third highest rated project on DistroWatch with a score of 9.09 out of 10. Features Void is a notable exception to the majority of Linux ...

Process Supervision
Process supervision is a form of operating system service management in which some master process remains the parent of the service processes. Benefits Benefits compared to traditional process launchers and system boot mechanisms, like System V init, include: * Ability to restart services which have failed * The fact that it does not require the use of "pidfiles" * Clean process state * Reliable logging, because the master process can capture the stdout/stderr of the service process and route it to a log * Faster (concurrent) and ability to start up and stop Implementations * daemontools daemontools-encore Derived from the public-domain release of daemontools Eye A Ruby implementation Finit Fast, Extensible Init for Linux Systems God A Ruby implementation immortal A Go implementation * PM2: A Process Manager for Node.js * Initng * launchd minit A small, yet feature-complete Linux init * Monit * runit Supervisor A Python implementation s6 Low-level process and service supervisi ...

Artix Linux
Artix Linux (or simply Artix ) is a rolling-release distribution based on Arch Linux that uses inits such as OpenRC, runit, s6, or Dinit, as opposed to Arch Linux's init systemd. Artix Linux has its own package repositories but, as a pacman-based distribution, can use packages from Arch Linux repositories or any other derivative distribution, even packages explicitly depending on systemd. The Arch User Repository (AUR) can also be used. Arch OpenRC began in 2012 and Manjaro OpenRC was subsequently developed alongside it. In 2017 these projects merged to create Artix Linux. Release history Artix initially offered two installation environments, a base command-line ISO image and the graphical Calamares installer based on LXQt desktop, with an i3 version following later. Those early versions featured the OpenRC init system. The latest installation media are available in a variety of desktop environments like LXDE, XFCE, MATE, Cinnamon and KDE Plasma 5. Additionally, two un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Init
In Unix-based computer operating systems, init (short for ''initialization'') is the first process started during booting of the computer system. Init is a daemon process that continues running until the system is shut down. It is the direct or indirect ancestor of all other processes and automatically adopts all orphaned processes. Init is started by the kernel during the booting process; a kernel panic will occur if the kernel is unable to start it. Init is typically assigned process identifier 1. In Unix systems such as System III and System V, the design of init has diverged from the functionality provided by the init in Research Unix and its BSD derivatives. Up until recently, most Linux distributions employed a traditional init that was somewhat compatible with System V, while some distributions such as Slackware use BSD-style startup scripts, and others such as Gentoo have their own customized versions. Since then, several additional init implementations ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devuan
Devuan is a fork of the Debian Linux distribution that uses sysvinit, runit or OpenRC instead of systemd. Devuan aims to avoid "lock-in" by projects like systemd and aims to maintain compatibility with other init systems to avoid detaching Linux from other Unix systems. History With the release of Debian 8 some developers and users were alienated due to the project's adoption of systemd and subsequent removal of support for other existing init systems. This decision prompted some Debian community members to start a fork of Debian without systemd. Instead of continuing the Debian practice of using Toy Story character names as release codenames, Devuan aliases its releases using planet names. The first stable release shared the Debian 8 codename '' Jessie''. However, the Devuan release was named for minor planet 10464. The first stable release of Devuan was published on May 25, 2017. Devuan 2.0.0 ''ASCII'' was released on June 9, 2018, and 2.1 ''ASCII'' was released on Novembe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AntiX
antiX () is a Linux distribution based on Debian Stable. It is comparatively lightweight and suitable for older computers, while also providing cutting edge kernel and applications, as well as updates and additions via the apt-get package system and Debian-compatible repositories. antiX specifically does not ship with or support the systemd init system. SysVinit is set as the default. * Version 19 antiX offers sysVinit and runit as a choice for the init system. * Starting with version 22 antiX is offered elogind-free for both 32-bit and 64-bit architecture. Window managers antiX comes with default SpaceFM Desktop Environment (DE) built on top of GTK library and IceWM as a Window Manager. antiX-full and antiX-base include these window managers: * Lightweight: Rox-IceWM (default), IceWM and SpaceFM-IceWM.

Process Identifier
In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels—such as those of Unix, macOS and Windows—to uniquely identify an active process. This number may be used as a parameter in various function calls, allowing processes to be manipulated, such as adjusting the process's priority or killing it altogether. Unix-like In Unix-like operating systems, new processes are created by the fork() system call. The PID is returned to the parent process, enabling it to refer to the child in further function calls. The parent may, for example, wait for the child to terminate with the waitpid() function, or terminate the process with kill(). There are two tasks with specially distinguished process IDs: ''swapper'' or ''sched'' has process ID 0 and is responsible for paging, and is actually part of the kernel rather than a normal user-mode process. Process ID 1 is usually the init process primarily responsible for starting and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Ruby On Rails
Ruby on Rails (simplified as Rails) is a server-side web application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. Ruby on Rails' emergence in 2005 greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Pyt ...
