Thank you.  The code seems to suggets that I just need to edit a
file called $BSDINSTALL_TMPBOOT/loader.conf.hardening but I will be
damned if I can find any such on my system, anywhere in my root
partition.  So I'm stumped.  To make matters even worse, the
output I get from "sysctl -a" doesn't even seem to list -any-
sysctl variable called "security.bsd.allow_destructive_dtrace", so
I am double stumped.
