Description: system-wide service supervision (as init system)
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.
.
This package provides /sbin/init, that boots your system and starts runit.
