Oh how I've waited for somebody to back up my views on systemd. If it were any good, I wouldn't have half the headaches I've had with upgrades and installations over the last couple of years or so and any bad words from LT about this were, IMHO, well deserved. systemd is a great example of somebody rewriting from scratch something that already existed (and did the job reasonably well but just needed a bit of fettling) and now, because everyone + dog wants to be "up to date" (i.e. using the latest fad), it's headache time for everyone that has to use the damn thing.
I'd say more, but it wouldn't be safe...
