I tend to agree, but wonder if it would not make more sense to tackle this from a different angle. Consider all the programs that could clobber a mounted file system. Would it make more sense if we somehow protected a mounted disk device from being clobbered? I am sort of thinking of the way amd mounts its disk devices exclusively, makes it difficult to get a dump, but effectively protects the device (well, at least the normal device, not the raw device). OTOH, this is a can of worms, no matter how you do it. ... JG
