Systemd is a decent init system, fast (ssd+systemd=10 sec from button press), and dependency resolution is quite good. The units are configurable in the /etc/systemd directory and take precedence over the (/usr)/lib/systemd units. It is not perfect but it works. I believe it is somewhat better that sysvinit especially in dependencies. You just need an After=foo.service or Wants=foo.service and systemd takes care of everything. I know this is supported by sysvinit but the whole numbering thing always seemed like a hack to me. Systemd gets it right.

That being said, I can't say I am a fan of the integration of other services within systemd, it seems somewhat bloated. And I certainly don't like the whole journal thing. When the journal becomes bigger it becomes considerably slower. And I don't get the point for binary logs. I mean, logs are just text, why overcomplicate things?

I've been using it for over a year in Arch it is really good as an init daemon, I believe it is definitely a step to the right direction especially for desktops/workstations, probably for mobile as well. The rest of the package though, I am not so sure.
