You can laugh but only 8 years ago I used to use dos 6.2 for making up rollout installers.
These days I presume they just boot them all straight to network.
Each person had 20 floppy's and 10 of you would fire 20 machines each and run round in circles giving the script the individual machines name and other bollocks. As soon as that 20 were done you were off to another 20 machines. By the time you had 1000 building it was back to the beginning to sort the printers and user accounts out.
