One thing thats coming in 1.1.3 is an mcp (master control process) and
associated init script for pacemaker.
This means that Pacemaker is started/stopped independently of the
messaging layer.
Currently this is only written for corosync[1], but I've been toying
with the idea of extending it to Heartbeat.
In which case, if you're already changing the option, you might want
to make it: legacy on/off
Where "off" would be the equivalent of starting with -M (no resource
management) but wouldn't spawn any daemons.
Thoughts?
[1] Which has an API call which allows Pacemaker to prevent Corosync
from shutting down if its still running.
So "service corosync stop" will fail if you didnt already run
"service pacemaker stop"
