So I built a *live-wd0root.img, installed that on a usb stick and
apparently my motherboard doesn't allow booting from usb stick.

So I decided to make a rescue or live cd iso (so I could boot from
cd and transfer to the temp boot drive) and neither are build.sh
options (the iso). And since floppy boot has been removed, the old
method:

  mkisofs -o output.iso -b i386/installation/floppy/boot-big.fs \ 
    -c boot.catalog -l -J -R -allow-leading-dots /cdsources

as described in https://www.netbsd.org/docs/bootcd.html#cdrecord
no longer works. It appears that the new method uses cdboot, but
I can't determine exactly how to make and use that.

Would be nice if https://www.netbsd.org/docs/bootcd.html was updated
to reflect how to build bootable cds now.
