If you are running RHEL or CentOS, you have no reason to upgrade.
the RHEL packages and the STABLE2 branch (cluster-2.03.xx) receives the
same set of bug fixes.
The main (and only) difference are the kernel modules. What comes with
RHEL/CentOS is built for that kernel/release combination while
cluster-2.03.xx follow upstream kernels (2.6.27 at this point in time).
Upgrading from what CentOS/RHEL to corosync/cluster-3.0.0.alpha1 has the
same problematics as described before.
I'm going to make him an offer he can't refuse.
