For any level of physical protection there is an adversary that could
breach it. So the first stage of protection is physical one, the second
is the breach detection that initiates clean shutdown. Problem is to
erase everything on this shutdown.
Or maybe I should start a reboot that hangs on "Enter passphrase for
/dev/ada0p3.eli" and erases the memory in the process?
