We provide many forms of installation media, but neither floppy nor

a hard drive image containing the installer bsd.rd.
I tested this on i386, it should work on amd64 too. It's just a bunch
of shell commands, save it to makeimage.sh or whatever. Maybe we
could integrate this into the distrib build makefiles, but I wanted to
get a procedure done first. I don't know what the best way to get a
disklabel on is, I just dumped a tiny bit of text into a file.
It's actually very similar to what builds the install.iso, but I
didn't do it as a makefile for now so it's easier for standalone users
to run.
It assumes you have a working bsd.rd in /. If you wanted to build
amd64 on i386, or vice versa, you'll have to fiddle with the files.

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
All this sudo'ing makes my head spin.
Just run the script as root and remove the tee workaround.
