Supervisor Alternatives

systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system.

OpenRC is a dependency-based init system that works with the system provided init program, normally /sbin/init. It is not a replacement for /sbin/init. OpenRC is 100% compatible with Gentoo init scripts, which means you can probably find one for the daemons you want to start in...

runit is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes. It runs on GNU/Linux, *BSD, MacOSX, Solaris, and can easily be adapted to other Unix operating systems.

Advanced process manager for production Node.js applications. Load balancer, logs facility, startup script, micro service management, at a glance.

The Sysvinit package contains programs for controlling the startup, running, and shutdown of the system.

eudev is a fork of systemd with the aim of isolating udev from any particular flavor of system initialization. This is a project started by Gentoo developers to ensure udev remains system initialization and distribution neutral.

The nosh package is a suite of system-level utilities for initializing and running a BSD or Linux system, and for managing daemons.

Finit is a small SysV init replacement with process supervision similar to that of daemontools and runit. Its focus is on small and embedded GNU/Linux systems, although fully functional on standard server and desktop installations.

Using the tooling in this repo, I am able to boot from linux to sinit as PID1, and from there to Emacs acting as PID2 using --script mode, performing all typical rc.boot system initialization using Emacs lisp until we hit the getty.

procd is a process and system init service for OpenWRT. It's less resource intensive as it's intended for embedded devices, works with busybox and uClib, hotplug2, libubox and ubus. It watches configuration files to start or restart services and init...

Chaperone is a lightweight alternative to process environment managers like systemd or upstart. Chaperone provides an extensive feature set, including dependency-based startup, syslog logging, zombie harvesting, and job scheduling.
