Systemd is the controversial project taking Linux by storm. Several Linux distros have or are in the process of switching over to systemd, namely Fedora, OpenSuse, Ubuntu, Debian and Arch Linux.

What’s the hullabaloo about systemd? Systemd is the replacement for the old SysV, the init system that initializes Linux on boot. Some detractors are saying that systemd is not Unix-like, whatever that means.
