Re: obsd boot hack (boot-modified-kernel-attack)

For BSD/OS systems, creating a /etc/boot.default file which loads
/bsd explicitly and does no -pause or -waitnl commands will force it
to boot the specified file with no chance for operator intervention.
As configured by default, the /etc/boot.default file does not load a
kernel, and the boot program will pause for 5 seconds allowing it to
be interrupted before loading the default kernel (/bsd).
