based on the other emails from Jerry recently, I'd assume that the usb 
drive is the only mass storage device he has in the machine, so /dev/sda 
should be predictable. But then, isnt this the exact issue that Labels' 
are supposed to resolve ?

Your recommendations of labeling the partition with something that is 
specific to the device ( label=USBROOT or label=USBKEYOSROOT ) might be 
a good 'middle path' here. Might need to do something similar for the 
swap and then sanity check /etc/fstab
