Interrupting boot process

[Krassimir Slavchev]

Hello list,

I use nanobsd (FreeBSD 8) and would like to prevent interrupting of the
boot process by hitting CTRL+C. All consoles are marked as insecure in
/etc/ttys.
The problem is that the /etc/rc.initdiskless can be interrupted at the
moment when /etc is empty and the result is dropping into a shell
without asking for a password. I have tried to trap the interrupt signal
from rc.initdiskless but no luck.

What is the appropriate solution of this problem?

Best Regards
