The debate began in late October, when the technical committee was asked to make an adjudication, and months of debate followed thereafter, before the choice was finalised to a decision between: systemd, a modern, default init system of many Linux distributions nowadays that significantly decreases boot times on Linux systems, but is tightly integrated to solely Linux; Canonical’s upstart, a modern init system that is found in Ubuntu; sysvinit, the existing default in Debian that is widely used and can trace its history back to the 1980s; and openrc, a Gentoo-backed init system that is similar to sysvinit in many respects.
