We've done things like that before, too.

I don't think you can boot a FreeBSD system from a FAT

That _might_ work, but I haven't tried it myself.

PXE would really be the cleanest and easiest way, and it's
also very easy to maintain. If you can't do that, maybe
you need to re-think your existing deplayment process and
make it more flexible ...?
Another possibility is to prepare a boot image, i.e. a file
containing boot sector and a UFS root partition with
wverything needed for bootstrapping (/boot/loader etc.,
kernel, base system). It doesn't have to cover the whole
disk, it should be just large enough for a base system and
some support software. It should contain a script which
configures the rest of the disk when it's booted (e.g.
set up remaining disk space, fetch packages from the net,

the image to the beginning of the hard disk, then reboot.

Right, Linux support for UFS is weak, not to mention UFS2.

The FreeBSD Handbook covers that topic (chapter 25.5).
