Abstract

Most modern mature OSes distributions allow users to tune set of installed packages by simple procedures like selecting install profile Basic CLI server or Rich GUI Workstation and many of them offer even more precision profiling to better suit user OS usage profile – like for example profile optimized by size and amount set of packages in CLI server mode to get close to ideal OS profile for Virtual Images creation.

This document present approaches and procedures how user can easily create this experimental prototypes of OpenSolaris install profiles – set of OS packages for OpenSolaris 200811, 200906 and prove then they are good fit for various user requirements.
