Welcome to cron.weekly issue #104 for Sunday, November 5th, 2017.
The year is 2047. What is obvious now could not have been predicted 30 years earlier. The rise of systemd has taken its toll on mankind. The systemd OS – or SOS as it’s called – has driven out all other operating systems. With the One True OS running on every computer, humanity was at the fingertips of its creators. Gone are the days of text-based logs files and transparent DNS resolvers.
We’ve said goodbye to systems that can reboot flawlessly. The remote controlled power bricks have seen unprecedented sales, resetting systems worldwide. When we finally learned to appreciate ‘unit files’, they were replaced by ‘mental files’, guessing our actions and wishes instead of having to define them beforehand. We can only look back at the very start of this all and think ‘if only we contributed to systemd instead of just complaining about it‘.
How’s that for a scary Halloween story? 😉
