Runit is an init scheme for Unix-like operating systems that initializes, supervises, and ends processes throughout the operating system. Runit is a "reimplementation" of the "seminal" daemontools[3] process supervision toolkit that runs on the Linux, Mac OS X, *BSD, and Solaris operating systems. Runit features parellelization of the start up of system services, which can speed up the boot time of the operating system.[4]

"In Unix-based computer operating systems, init (short for initialization) is a daemon process that is the direct or indirect ancestor of all other processes. It automatically adopts all orphaned processes. Init is the first process started during booting, and is typically assigned process identifier number 1. Init continues running until the system is shut down." (from init)

Design[edit]

Runit focuses on being a small, modular, and portable codebase. Runit is split into three stages: one time initialization, process supervision, and halting or rebooting. While the first and third stages must be adapted to the specific operating system they are running on, the second stage is portable across all POSIX compliant operating systems.[5]
