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.
