The Grumpy Editor's guide to surviving the systemd debate

"They tried that and failed. Approx 1% of Wheezy users replaced sysvinit with systemd, compared with e.g. approx 30% who replaced exim4 with postfix."

I think that using these statistics light that might be very misleading. I don't know if I'm representative, but taking my case as an example :

- Systemd support in wheezy seemed just not ready for prime time to me [1]. The couple dozens of wheezy servers that I manage still run sysvinit. OTOH, I started running systemd (including as PID 1) on the few jessie systems I have immediately (laptop and home jukebox).

- Most of my wheezy systems are installed from an OpenVZ template that comes with postfix, whereas I was much more familiar with the default exim4. Turns out that on most of them I don't want anything more complicated than sending alerts to root, so I don't care. But I didn't switch to postfix myself.

[1] maybe I was wrong thinking that, that's not the point.
