</div>Not completely true. It is present in Debian for 2 years - long time before considering systemd. And it is present in<br>
Debian stable already:<br>

The recent publicity was about Debian's decision to switch the default starting with Debian 8 "jessie".</div>

Many people are still running Debian 7 "squeeze", to the point where a subset of squeeze ("squeeze-lts") is still receiving support and security fixes beyond Debian's normal policies.</div>
