	On upgrades, we now must determine if we are upgrading from monolithic
	xfs or modular xfs by checking for the existance of the old monolithic
	xfs config file.  If found, we know it is a monolith->modular upgrade,
	so we set this flag file in order for xfs.init to perform a "restart"
	instead of a "reload" in the 'condrestart'.  See bug #173271 for
	details.
