installer choices – explaining certain keys

Hello all, So I understand the basics of how to make and use an installer choices file. Normally i stick to the items that I need and don't pay attention to anything else in the list. This is the first time I am working from a DVD that came with a computer, instead of the retail DVD. As such, I noticed some entries that were new to me and was wondering if anyone knew their exact use, if they should be included, excluded or simply not touched. Round one: choiceIdentifier WelcomeToLeopard.pkg -- choiceIdentifier CPU_UG_macpro.pkg -- choiceIdentifier CPU_AHT.pkg -- choiceIdentifier CPU_RegionalBoot.pkg -- choiceIdentifier CPUHelpFiles.mpkg Are those going to mess with my hardware independent image?
