Great, exactly what I needed, thanks.

I ended up with following script:


DISTRIBUTIONS="base.txz kernel.txz lib32.txz"
export DISTRIBUTIONS

bsdinstall checksum
bsdinstall hostname
bsdinstall scriptedpart ada0 gpt { 512K freebsd-boot , 2G freebsd-ufs / ,
4G freebsd-swap , 8G freebsd-ufs /var , 4G freebsd-ufs /tmp , auto
freebsd-ufs /usr }
bsdinstall mount
bsdinstall distextract
bsdinstall config
bsdinstall entropy

#!/bin/sh

sysrc ifconfig_DEFAULT=DHCP


While I feel a bit wrong using `bsdinstall` command in the preamble part,
but it works pretty nice. However, the script part doesn't seem work. The
last window I see in the installer is "No root partition is found. The root
partition must have a mountpoint of /". After I hit OK, the script ends and
no "sysrc" command is run.

What am I doing wrong now?
