BZZT.  Thanks for playing, but you're wrong.  <CTL><ALT><DEL> means
nothing to *any* OS unless the OS allows does something special with
that sequence of keys.  In FreeBSD, it used to mean absolutely nothing
until I added the ability for it to reboot the system in the same manner
as people were used to under DOS/Windows.

When you press <CTL><ALT><DEL> in FreeBSD you are basically doing the
same thing as a 'shutdown -h now'.

No disk corruption, no data loss.  Now, whether or not you think it's a
good thing to have is up to you, but you can safely do it under FreeBSD.

However, you can't do it inside of X unless you patch the X-Server to
pass the keystrokes to the kernel, which is actually a pretty trivial
patch, but it isn't done by default.

Read the man pages on syscons, kbdmap, and kbdcontrol for more information.
