I've updated it to:

[03:27 PM] beekhof at f17 ~/Development/sources/pacemaker/devel ☺ # mcp/pacemakerd --help
pacemakerd - Start/Stop Pacemaker

Usage: pacemakerd mode [options]
Options:
 -?, --help 		This text
 -$, --version 		Version information
 -V, --verbose 		Increase debug output
 -S, --shutdown 		Instruct Pacemaker to shutdown on this machine
 -F, --features 		Display the full version and list of features Pacemaker was built with

Additional Options:
 -f, --foreground 		(Ignored) Pacemaker always runs in the foreground
 -p, --pid-file=value		(Ignored) Daemon pid file location

This is on non-linux right?
I think Angus was of the opinion that $thing_i_cant_remember did reference counting a bit differently on non-linux.
I'm not sure he made much progress with it.  Can you confirm which arch this is before we continue?
