looks like the pacemaker plugin is missing :-(

i'll fix that tomorrow.  in the meantime, if service_crm.so is part of  
the package somewhere, copy it to the above directory with a .lcrso  
suffix and restart ais...
it should "just work"

heartbeat-common contains a number of useful libraries and tools (such  
as the lrmd) which are useful regardless of which cluster stack one is  
using.
In fact clplumbing is useful even if you're not doing clustering at  
all - there is a lot of good stuff in there.

More than anything else, its also not accurate, since the package  
comes from the heartbeat project not pacemaker.

I could try and maintain those parts of the code in pacemaker but I  
don't have the intention, time or expertise to do so.
There is simply no benefit in trying to.

Everyone repeat after me... Pacemaker is NOT a fork of Heartbeat.  The  
project contains the CRM and nothing more.
