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. -- Duncan - List replies preferred.
