I think you've taken that far too literaly. My understanding of it is to protect against a) brute force retardation b) dumb attackers.
The advice weakens the security of your system, because it means I just need to compromise your unprivileged account (in which you run your browser, mail client, and so on) to own the entire box. As for the benefits, care to elaborate? I'm not sure what a) and b) really mean. If you're worried about brute-force, don't use trivial passwords. If you worry about opportunistic attacks, do that and then patch your stuff every now and then. /mz _______________________________________________ Full-Disclosure - We believe in it.
