Here's a version without the disklabel file, using EXAMPLES section from softraid(4). I modified gzip invocation to avoid handling temporary files, but I end up wondering if it's worth it... I also added missing sudo invocation #!/bin/sh set -e dd if=/dev/zero bs=1k count=3584 of=disk.img sudo vnconfig vnd0 disk.img sudo fdisk -y -i vnd0 printf "a\n\n\n\n\nw\nq\n\n" | sudo disklabel -E vnd0 sudo newfs -i 512000 vnd0a sudo mount /dev/vnd0a /mnt gzip -9 -c /bsd.rd | sudo tee /mnt/bsd >/dev/null sudo cp /usr/mdec/boot /mnt/boot sudo /usr/mdec/installboot /mnt/boot /usr/mdec/biosboot vnd0 sudo umount /mnt sudo vnconfig -u vnd0 Cheers
