runit is a cross-platform Unix init scheme with service supervision; a
replacement for sysvinit and other init schemes. It runs on GNU/Linux, *BSD,
Mac OS X, and Solaris, and can easily be adapted to other Unix operating
systems. runit implements a simple three-stage concept. Stage 1 performs the
system's one-time initialization tasks. Stage 2 starts the system's uptime
services (via the runsvdir program). Stage 3 handles the tasks necessary to
shutdown and halt or reboot.
