I quote from your above test: "usr/home (or, may be, just /home)"

On a freshly installed 10-STABLE snapshot:
root at zbeastie:~ # ls /home
ls: /home: No such file or directory
root at zbeastie:~ # ls /usr/home
root at zbeastie:~ # df -h /usr/home
Filesystem        Size    Used   Avail Capacity  Mounted on
zroot/usr/home     17G     96K     17G     0%    /usr/home

Now compare that to the following code:
http://svnweb.freebsd.org/base/head/usr.sbin/bsdinstall/scripts/zfsboot?view
=markup

Read: There is a /usr/home already -- what's the issue?

Perhaps; but if you're really deploying that many systems (to which it is
a need that each be setup in the same [custom] manner), you really
out to make a custom installer.

Just rip open the installer ISO, create the following file:

FILE: /etc/installerconfig
ZFSBOOT_DATASETS="
	# your custom settings here -- see /usr/libexec/bsdinstall/zfsboot
" # END-QUOTE

Then repack the ISO and use that instead of the generic release media.
