Systemd poettering
Systemd is a system and session manager for Linux that is compatible with SysV and LSB init scripts. It provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. Systemd implements an elaborate transactional dependency-based service control logic and can work as a drop-in replacement for sysvinit.
