The Tragedy of systemd
Benno Rice https://2019.linux.conf.au/schedule/presentation/156/ systemd is, to put it mildly, controversial. As a FreeBSD developer I decided I wanted to know why. I delved into the history of bootstrap systems, and even the history of UNIX and other contemporary operating systems, to try and work out why something like systemd was seem as necessary, if not desirable. I also tried to work out why so many people found it so upsetting, annoying, or otherwise rage-inducing. Join me on a journey through the bootstrap process, the history of init, the reasons why change can be scary, and the discovery of a part of your OS you may not even know existed. linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
