Nothing shameful here. Installation is easily scripted, but you still
have to learn how to do that.

They have to support it in installer (e.g. due to the way they distribute
the system), NetBSD doesn't have to do that.
Seriously, if you do need to automate it, you can get it done within
few hours even if you're not a great coder.
The process goes as this (read man pages to understand what's going on):
fdisk -v -u -f -i -0 -s 169/63/2029041 wd0
# you only need to make your script to find the last number by another fdisk
fdisk -v -f -a0 wd0
disklabel -i wd0 # or this
disklabel -FR wd0 /tmp/cf.label # you only need to learn how to generate
newfs wd0a; mount /dev/wd0a /target
cd /target; for s in base etc text man ...; do pax -zrpe -f
for s in kern-GENERIC modules; do sudo pax -zrpe -f
cp /target/usr/mdec/boot /target/boot
/usr/sbin/installboot -vf -o timeout=2 /dev/rwd0a /target/usr/mdec/bootxx_ffsv1
Perhaps it can be simplified more, I don't remember.
I couldn't find more detailed notes from my past project.
