Nitro: A Minimal Linux Process Supervisor and Init System
By
todsacerdoti
A second-rack bagel that's nearly first-rack. Tasty stuff.
Summary
Nitro is a lightweight process supervisor and init system designed for Linux systems. It functions as a minimal alternative to traditional init systems, operating through a directory-based configuration approach where services are defined via scripts in /etc/nitro. The system supports setup scripts that run before services start and run scripts that maintain service execution. It's designed for embedded systems, containers, minimal environments, and as a learning tool for init systems.
