Not being that cluey on the internals of the FreeBSD console internals, it's more a curiosity question than anything. A definitive "yes/no/damned if I know" from those who *are* capable of answering would save a relative novice hacker from wasting time :) I can already see a nice simple problem, in that it would only work after login...if you need to shutdown because you can't login for some reason (exhausted swap space because of a nasty process?), then this makes things difficult...but it should help machines in public places around people who have too much curiosity. -- Sean Winn email: sean@gothic.net.au, sean@cynet.net.au All opinions valued at $0.02, and not subject to inflation.
