OpenRC

OpenRC is a dependency based init system that works with the system provided init program, normally /sbin/init. It is not a replacement for /sbin/init. OpenRC is 100% compatible with Gentoo init scripts, which means you can probably find one for the daemons you want to start in the Gentoo Portage Tree. OpenRC, however, is not exclusively used by Gentoo Linux and can be used on different Linux and BSD systems.

Features
OpenRC provides a number of features touted as innovative by recent init system like systemd or upstart like hardware initiated initscript run or cgroups support without requiring large layout changes to accomodate the radically different design and dependencies required by systemd.
