If the person trying to get your data has physical access, there is very
little way to stop them from, eventually, getting your data. It is secure
in the sense that short of physical access, there are very few ways to
break in.

I believe that if you change /etc/ttys to list "console" as "insecure"
rather than "secure", it will prompt for the root password before
starting the single-user shell.  I've never actually tried it.

Asking for the password in single-user mode won't slow the intruder down
very much.  If they can type "boot -s" they can stick a floppy in the
slot first before they type it.
