openrc 0.18.3-1 (s390x binary) in ubuntu xenial

 OpenRC is a dependency based init system. It provides support for System V
 init, for booting, changing runlevels, starting and stopping services, and
 shutting down.
 .
 Originally written as a Gentoo project, OpenRC aims at being
 platform-agnostic. It works equally well on Linux, BSD and Hurd.
 It supports the traditional init system in Debian in addition to many
 alternatives. OpenRC is implemented in C in a small, simple and
 efficient way, making it easy to understand, extend and reuse.
 .
 This package provides the runlevel change mechanism.
