boot -s - can i detect intruder

[Nikolay Kanchev]

Hi list

Several people have physical access to my FreeBSD box and I have the feeling
that somebody try to get access with boot -s options . Can I log activity
after boot -s option (change user password, install software and etc.).
I use boot -s and change user password, but after reboot i can't find this
atcivity in log files.
The BSD box is shutdown and run again many time at day.

Best regards,

Nikolay Kanchev
