Are you trying to do an installation of Solaris/OpenSolaris and then transfer that installation to multiple machines? If so, read up on Flash archives: (http://docs.sun.com/app/docs/doc/819-2397/flash-24?l=en&a=view&q=flash). This technology in Solaris/OpenSolaris allows you to perform an install and then create an archive that you can deploy to other machines (of the same architecture type). This seems a better fit for what you're trying to do (if I understand you correctly). Cheers, -- Glenn
