I've not yet made the leap, as the benefit of faster boot really doesn't affect me between systems that're always on and laptops that typically spend 75% of their time asleep, rather than ever getting turned off, so I'm in no position to speak for or against the whole of systemd's changes... but one issue I've had with the claimed benefits is the reduction in size compared to startup scripts like /etc/init.d/sshd ... based on that service declaration above, it's a horribly unfair comparison. /etc/init.d/sshd is doing a lot more than simply starting/stopping the service and dropping all of that functionality, then claiming "these few lines serve the same purpose" isn't an equal comparison. It would still be a (notable, at that) drop in size if the shell script was redone to provide exactly the same set of features, then compared, but that size difference wouldn't have the same shock value as the comparison against 80+ lines. The argument that those functions should be handled by the service rather than the service handler is for another day, 'course. I'll eventually get around to switching to play with systemd, at the very least to learn its quirks enough to work with it, and it's very helpful to have a clearly stated set of _favorable_ comments on it (compared to the majority of less favorable commentary) to look forward to, so don't take my having one issue with the list as anything against either the list as a whole or your effort in putting all that together, as both are very much appreciated.
