	Hi;

	Well, I dont know much about the udev rules, but the script
itself can set a flag on initial plug, and just exit if that flag
is already set. eg. if /dev/mapper/MySecureVol exists...
	Even if you think you have a udev solution, it still might
make sense to have the script sanity test the state; if the conditions
the script are meant to enact have already happened, it need not act.
