heartbeat 1.2.3-12ubuntu0.2 (amd64 binary) in ubuntu breezy

 heartbeat is a basic heartbeat subsystem for Linux-HA.
 It will run scripts at initialisation, 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)
