># heartbeat     Start high-availability services
>#
>### BEGIN INIT INFO
># Description:
>#   heartbeat is a basic high-availability subsystem for Linux-HA.
>#   It will start services at initialization, and when machines go up or down.
>#   This version will also perform IP address takeover using gratuitous ARPs.
>#   It works correctly for a 2-node configuration, and is extensible to larger
>#   configurations.
>#
>#       It implements the following kinds of heartbeats:
>#               - Bidirectional Serial Rings ("raw" serial ports)
>#               - UDP/IP broadcast (ethernet, etc)
>#               - UDP/IP multicast (ethernet, etc)
>#               - Unicast heartbeats
>#               - "ping" heartbeats (for routers, switches, etc.)
>#               (to be used for breaking ties in 2-node systems)
>#
># Short-Description: Startup script high-availability services.
