[Casper] Upgrading from Tiger to Leopard

[Bryan Vines]

David,

We began exploring the idea of having the user data on a separate  
partition for the same reason -- future OS upgrades will hopefully be  
less painful. We have been using a three-partition scheme: Restore,  
Macintosh HD, and Data.

Our partition sizes are:
     Restore: 15GB
     Macintosh HD: 30GB or so
     Data: The rest of the drive.

We've found we need at least an 80GB drive to allow the users about  
30GB of space. We deployed a few Tiger machines with this partitioning  
scheme, but then we went ahead and switched to deploying Leopard  
(mostly because of laptops which would only run Leopard).

User homes go on Data, so if the main boot partition ends up hosed, we  
can restore it from our standard configuration and get the user up and  
running again with a minimum of fuss.

We're now moving our older installed base to Leopard. We have to go  
touch each machine, either to repartition its hard drive or install a  
larger one. We're hoping we won't have to do that when Snow Leopard  
rolls around.
