[Casper] Partitioning Macintosh HD during Imaging

[Ryan Harter]

In theory the Casper Installer could get confused when you repartition  
the space, as to what to set the boot device too.  You could perhaps  
add to your script after you partition the drive to 'bless' it.  This  
way, even if Casper forgets to set the boot volume, you have already  
done it manually.

I'm not entirely up to speed with the bless command, but I think  
Bombich has some good info on it, or you could 'man bless'.

Hope it helps,
