[Casper] Upgrading from Tiger to Leopard

[Daniel Farnworth]

Just chiming in with my 2 pence worth, we approach this in a slightly  
different way for a number of reasons.

I'm not sure about other applications, but we discovered that Avid  
applications do not like symlinks when it comes to /Users which they  
still rather irritatingly use to store various things (mostly in / 
Users/Shared)

What we do instead is have a separate Homes or Data partition and  
then use fstab to mount this directly to /Users, this gives us the  
best of both worlds, user data on a separate volume and no symlinks  
involved. It also this works a treat for the Avid apps as they just  
see that the /Users directory is in the correct place. I have a pre- 
install script that we use to do this for us if anyone is interested.

Cheers
Dan
