[Openais] first time install of corosync, openais and pacemaker on ubuntu 9.04

[Andrew Beekhof]

Unless you plan on using the dlm and/or ocfs2... I'd simplify your
life and just remove the openais related packages for now.

You can still follow the instructions from:
   http://clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/s-install-enable.html#s-install-enable-ais

But just substitute the corosync.conf file whenever openais.conf is mentioned.

I thought that the /etc/ais/openais/openais.conf file would override the /etc/corosync/corosync.conf file, but it seems that it's the other way around.  Even when you use /etc/init.d/openais to start, the /etc/corosync/corosync.conf file is used.

When I change the /etc/init.d/openais to call out openaissserviceenable, then it loads that module correctly.  Maybe I have an old or outdated /etc/init.d/openais??
