Whitelists would need to be reasonably specific, anyway (not "all thinkpads"), so it just means "don't do it on certain R50e", or whatever. It is no easy problem, and the fix might not be as simple as one could wish, either. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
