Description:
system-wide service supervision
runit is a collection of tools to provide system-wide service supervision and to manage services. Contrary to sysv init, it not only cares about starting and stopping services, but also supervises the service daemons while they are running. Amongst other things, it provides a reliable interface to send signals to service daemons without the need for pid-files, and a log facility with automatic log file rotation and disk space limits. . runit service supervision can run under sysv init or replace the init system completely. Complete init replacement needs to be done by hand (see https://bugs.debian.org/861536)
