Nitro: A tiny but flexible init system and process supervisor
, a tiny but flexible init system and process supervisor Overview Nitro is a tiny process supervisor that also can be used as pid 1 on Linux. There are four main applications it is designed for: - As init for a Linux machine for embedded, desktop or server purposes - As init for a Linux initramfs - As init for a Linux container (Docker/Podman/LXC/Kubernetes) - As unprivileged supervision daemon on POSIX systems Nitro is configured by a directory of scripts, defaulting to /etc/nitro (or the first command line argument).
No configuration compilation steps needed, services are simple directories containing scripts. Finally, nitro reboots or shuts down the system; or just exits when it was used as a container init or unprivileged supervisor. I’m standing on the shoulder of giants; this software would not have been possible without detailed study of prior systems such as daemontools, freedt, runit, perp, and s6.
