Well, this page says otherwise.

With just three commands, you can do wonders.

losetup /dev/loop0 lunar-1.5.1-i686.iso
mount /dev/loop0 /mnt -o ro
chroot /mnt /sbin/lunar-install

Just replace the /sbin/lunar-install command with an appropriate one,
that is all.

chroot is very powerful! In fact you can run linux  inside linux very
easily using chroot
whereas uml is somewhat painful.

Debian also gives a very easy procedure for USB keyflash boot. It is
really very straightforward.

I am looking out how to do it for *BSD.
