# heartbeat     Start high-availability services
#
# Author:       Alan Robertson	<alanr@unix.sh>
#
#		This script works correctly under SuSE, Debian,
#		Conectiva, Red Hat and a few others.  Please let me know if it
#		doesn't work under your distribution, and we'll fix it.
#		We don't hate anyone, and like for everyone to use
#		our software, no matter what OS or distribution you're using.

#
### BEGIN INIT INFO
# Description: heartbeat is a basic high-availability subsystem.
#	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
#		 and monitoring networking availability)
#
# Short-Description: High-availability services.
# Required-Start: $network $time $syslog
# Required-Stop: $network $time $syslog
# Default-Start: 3 5
# Default-Stop: 0 6

#
#  Changed the code so that in the case of nice_failback there is no waiting for
#  the other side to give up resources, because we negotiate this in advance.

#
#  Revision 1.1  2001/05/09 23:21:21  mmoerz
#  autoconf & automake & libtool changes
#
#  * following directories have been added:
#
#    - config	will contain autoconf/automake scripts
#    - linux-ha	contains config.h which is generated by autoconf
#  		will perhaps some day contain headers which are used throughout
#  		linux-ha
#    - replace	contains as the name implies replacement stuff for targets
#  		where specific sources are missing.
#
#  * following directories have been added to make a split up between c-code
#    and shell scripts and to easy their installation with automake&autoconf
#
#    - heartbeat/init.d		containment of init.d script for heartbeat
#    - heartbeat/logrotate.d	containment of logrotate script for heartbeat
#
#    - ldirectord/init.d		similar to heartbeat
#    - ldirectord/logrotate.d	similar to heartbeat
#
#  * general changes touching the complete repository:
#
#    - all Makefiles have been replaced by Makefile.ams.
#
#    - all .cvsingnore files have been enhanced to cope with the dirs/files
#      that are added by automake/autoconf
#      Perhaps it would be a nice idea to include those files, but the sum
#      of their size if beyond 100KB and they are likely to vary from
#      automake/autoconf version.
#      Let's keep in mind that we will have to include them in distribution
#      .tgz anyway.
#
#    - in dir replace setenv.c was placed to available on platform where
#      putenv() has to be used since setenv is depricated (better rewrite
#      code -> to be done later)
#
#  * following changes have been made to the files of linux-ha:
#
#    - all .cvsignore files have been changed to ignore files generated by
#      autoconf/automake and all files produced during the build-process
#
#    - heartbeat/heartbeat.c:	added #include <config.h>
#
#    - heartbeat/config.c:		added #include <config.h>
#
#  * following files have been added:
#     - Makefile.am: see above
#     - configure.in: man autoconf/automake file
#     - acconfig.h: here are additional defines that are needed for
#  		 linux-ha/config.h

#  		into a useable form

Moved logging directives to the top of the sample ha.cf. Incremented version in master Makefile to 0.4.7apre2.
