[Casper] Partitioning Macintosh HD during Imaging

[Miles Leacy]

What
are you booted from when you perform the partitioning?  Tiger or Leopard?
The following command is what I typically use.
diskutil partitionDisk disk0 3 HFS+ Macintosh\ HD 40G HFS+ Restore 20G
HFS+ Data 0b
Note that the command above will create a 40 GB Macintosh HD, a 20 GB
Restore (highly recommended), and the "0b" size notation translates to
all available space.  Using "0b" allows you to partition any drive
without worrying about leaving unused free space on the disk.
I'm not familiar with the single quotes on a volume name.  I've always
just escaped the necessary characters.  Here's the command I would use
given the parameters listed in your script...

/usr/sbin/diskutil partitionDisk disk0 2 HFS+ Macintosh\ HD 50G HFS+ data 23G
