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,
