What does the whole path for the scsi device look like in sysfs?  I
think there's probably a bug in the NUMBER matchup that gets this wrong
right now (I only tested it with PCI devices, and need to get the
automated test framework up and running soon...)

This should work, but is there a better way to uniquely identify this
device in sysfs?  Any specific sysfs file for this device that would
make a LABEL rule an easier thing to do?
