[Pacemaker] Pacemaker requirements

[Michael, Benjamin P. (GSFC-690.0)[CATHOLIC UNIV OF AMERICA]]

Am somewhat confused with the requirements for Pacemaker.  This is what I think I understand on the current state.  If I have the following right would appreciate an affirmative.

1.  The opensuse repo is no longer supported and the clusterlabs repo is the current officially supported one.

2.  Corosync is a subset of Openais.  Corosync is the default to now use with Pacemaker and openais only has to be installed if using ocfs or a few other programs.  

5.  I have a cluster I setup late 2009 using the opensuse repo.  Working fine with openais from base CentOS 5.4.  If I upgrade pacemaker to 1.0.8 am I still alright to continue to use the openais from CentOS 5.4 or is there some specific reason to update to the openais and/or corosync in the repo?

Thanks for the help.

Pat
