I had to do all these "bsdinstall" invocations in the preamble because I
wanted to set up partitions in my way. It turned out that the value of
PARTITIONS variable is directly passed to "bsdinstall scriptedpart", so my
installerscript got reduced to

DISTRIBUTIONS="base.txz kernel.txz lib32.txz"
PARTITIONS="ada0 gpt { 512K freebsd-boot , 2G freebsd-ufs / , 4G
freebsd-swap , 8G freebsd-ufs /var , 4G freebsd-ufs /tmp , auto freebsd-ufs
/usr }"

#!/bin/sh

sysrc ifconfig_DEFAULT=DHCP

It now works, and even the second part gets properly executed.

However, no boot loader gets installed. Skimming through "bsdinstall
bootconfig" source reveals that it only supports installing boot files for
UEFI loader. What should I do in case of BIOS?
