This is nice of you to share your documentations.  However, this is not
really what I am looking for.

I am not really interested in proof of concepts.  Those documentations
that would show the actual setups that are in use would be useful for me
to start off with.

I saw that cfengine is mentioned for management of the Nagios
configuration
files across the servers. It seemed interesting.  Using SCP with keys
was
part of my original plan.  This may change or it would not.

Any other information about how a failover can occur for a slave when
the
master goes down?
