I'd like to know if it is at all possible as I have to install Tiger on 7 identical G4's and would much rather install it once on a firewire drive, clone it to all 7 G4's, and change the user names to suit. But recently I returned an iBook to Apple for repairs, when I recieved it back complete with new HD they had installed system with the user name Admin/admin. I rang and asked how to change the name and was told I'd have to reinstall.
