Runit: Service Supervision Suite for Unix-like Systems

A lightweight and customizable service supervision suite used to control processes and services on Unix-like operating systems, following a simple yet robust process supervision scheme.

What is Runit?

runit is an open-source process supervisor and init scheme for Unix-like operating systems. It was designed to be lightweight, customizable, and to follow Unix philosophy of doing one thing well.

Some key features of runit include:

• Simple yet robust process management using a single supervisor process
• Fast and reliable daemontools-compatible process supervision
• Init scheme that allows service supervision without PID 1 modifications
• Easy service monitoring and log management
• Minimal resource usage and overhead

runit consists of three core utilities - runsv, runsvdir, runsvc - that work together to enable process monitoring and automatic restarting. Services are defined per application, each with its own supervising process runsv watching over the main application process.

The runit init scheme allows using runit process supervision without having to replace system init daemon. This provides compatibility with SysV init scripts while still benefiting from advanced service supervision capabilities.

Overall, runit is a lightweight yet full-featured process control system. Its modular design makes it customizable for different needs, while still emphasizing simplicity, speed and reliability in process management.
