create netinstall from new macbook
I have some new Macbooks that have 10.8.3 out of box then again for 10.8.5 once I update it all to that version.
Normally I use Disk Utility to make a .dmg image that I than use to restore or mirror if needed at a later date.
Now I have read more and see there is a NetInstall option that might be faster for me.
How do I make the required OS X install Source?
I have tried firewire target drive but the NetInstall option is greyed out.
I want to do this for my 10.6, 10.7, 10.8, and when I make the switch 10.9 also.
