I think there's been a certain amount of confusion with regards to Heartbeat 
and Pacemaker (and their versions), so I
wonder if those involved (Lars, Andrew, Alan?) would clarify the following 
assumptions:

Pacemaker 0.6.x can be used as a replacement for the CRM in heartbeat 2.1.3 
(but NOT 2.1.4)?

In future, both Heartbeat AND Pacemaker will be required to provide the 
functional equivalent (broadly speaking) of
2.1.3 with its CRM, as Heartbeat itself won't have a CRM?

Pacemaker's NOT a fork or replacement for Heartbeat.  If I understand 
correctly, Pacemaker is so named because it's
required for Heartbeat to work in much the same as a pacemaker is required to 
maintain a stable heart rhythm?


I think it might be worth highlighting the incompatibility between Pacemaker 
and 2.1.4 (and *why*) on the Wiki page
http://www.clusterlabs.org/mw/Install

Under "First Steps" on that page, should

 export STACKS_SUPPORTED="--with-ais-support --without-heartbeat-support"

be

 export STACKS_SUPPORTED="--without-ais-support --with-heartbeat-support"

When building Heartbeat+Pacemaker? I assume the former applies when building 
OpenaAIS+Pacemaker
