今更ながら install boot (the same entry 6 Mo ago)

NetBSD/x86 ffsv2 Primary Bootstrap

Boot failed (errno 2): Can't open /boot

Recently I'm getting above issue.

using sysinst Advent calendar 2016
NetBSD/amd64 11.99.1 (but not limited to)
RAID1 configuration (by sysinst)
manual installboot is necessary

After usual sysinst, I would do

mount /dev/raid0a /mnt
chroot /mnt
mount -a
cd /usr/mdec

installboot -fv -t raid /dev/wd0a bootxx_ffsv1 /boot
installboot -fv -t raid /dev/wd1a bootxx_ffsv1 /boot
raidctl -A softroot raid0

The issue is:

Is raid0 by above setup is ffsv1 or ffsv2 (See bellow, saying ffsv1)
Is destination partition correct ?
