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. -- Devin
