Analysis of information sources in references of the Wikipedia article "Systemd" in English language version.
systemd uses many Linux-specific features, and does not limit itself to POSIX. That unlocks a lot of functionality a system that is designed for portability to other operating systems cannot provide.
systemd defines itself as a system and service manager. The project was initiated in 2010 by Lennart Poettering and Kay Sievers to create an integrated set of tools for managing a Linux system including an init daemon.
Yes, it is written systemd, not system D or System D, or even SystemD. And it isn't system d either. Why? Because it's a system daemon, and under Unix/Linux those are in lower case, and get suffixed with a lower case d.
ConsoleKit is currently not actively maintained. The focus has shifted to the built-in seat/user/session management of Software/systemd called systemd-logind!
...Knoppix 'boot process continues to run via Sys-V init with few bash scripts that start the system services efficiently sequentially or in parallel. (The original German text: Knoppix' Startvorgang läuft nach wie vor per Sys-V-Init mit wenigen Bash-Skripten, welche die Systemdienste effizient sequenziell oder parallel starten.)
...script-based KNOPPIX system start with sysvinit
It certainly is not something that comes with systemd from upstream.
The recently released openSUSE 12.2 does migrate from SysVinit to systemd
... a slice ... is a concept for hierarchically managing resources of a group of processes.
