runit-run binary package in Ubuntu Lunar amd64

 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 service file to start runit supervision via systemd
 and an entry in /etc/inittab that respawns the supervision tree for sysv
 users.
