------------------------------------------------------------------------
This is a condensed version of OpenBSD FDE encryption FAQ.
Boot installer, drop to shell with "s"
# cd /dev && sh MAKEDEV sd0 sd1
# dd if=/dev/urandom of=/dev/rsd0c bs=1m
# fdisk -iy -g -b 960 sd0 # GPT / without -g and -b for MBR
# disklabel -E sd0
Note, switch to kbd en before setting the password as this is
what you have on the boot prompt.
# bioctl -c C -l sd0a softraid0
# dd if=/dev/zero of=/dev/rsd1c bs=1m count=1
Ctrl+D to restart the installer. Choose sd1 as install target.
