Ubuntu OEM Install
This is usefull for creating a template to clone from.
At the initial install screen when booting up a Ubuntu installation image, hold shift and press f4. This will let you select the OEM install mode. Go through the setup on-screen and then restart te VM. Login using the account you created during setup and make any changes you want.
Once you have everything configured the way you want it, clone the machine and run oem-config-prepare. This command can also be run before cloning the VM as it requires a reboot. Now you’ll go through another setup process and it will ask you to create a new user account to be used with the system.
