systemd 217-1ubuntu1 (ppc64el binary) in ubuntu vivid

 systemd is a replacement for sysvinit. It is dependency-based and
 able to read the LSB init script headers in addition to parsing rcN.d
 links as hints.
 .
 It also provides process supervision using cgroups and the ability to
 not only depend on other init script being started, but also
 availability of a given mount point or dbus service.
 .
 Installing the systemd package will not switch your init system unless you
 boot with init=/bin/systemd or install systemd-sysv in addition.
