Package runit: Information

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.
