That's a good idea, but minor detail, it'd need to resolve to specific 
block-device major:minor comparison; it couldn't be a simple device-path 
blacklist, because device paths are routinely symlinked.

I guess that's obvious from a kernel dev perspective, but perhaps not so 
much from an admin-user perspective, where the device-path /is/ often 
considered the device.
