Just a simple question concerning the use of Ctrl-Alt-Del; would it be 
possible to only make the reboot usable only if it was root logged into 
the currently visible vty? 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.
