> My biggest concern is that distros like Debian and CentOS, whose goals normally include stability to the point that they are often railed against for including old, sometimes too old software, have adopted Systemd before it had any real rollout and experience. That's a bit disingenuous, Fedora 15 (released May 2011) was the first distribution to enable systemd by default, so there were at least 2 years of "rollout and experience" when Debian 8 (April 2015) and CentOS 7 (July 2014) switched. And at least in the case of Debian, it was already available as an option since 2012.
