The build-temp-vm script will perform the same logic as the build-iso script, the only difference being it will not perform ISO extraction logic whenever the VM is closed. Changes made inside the temporary VM will NOT be preserved. The AUTO-VM bootstrap ISO (which similarly has the system and kernel rebuilding logic on boot but has the ISO generation steps removed) is created by slightly modifying the standard AutoFullDistro0.ZC script file, then using sync.sh to sync the repo contents and update the AUTO iso. Since this setup exists separate from the ISO process, the modified AUTO iso can simply be renamed to AUTO-VM.ISO and the default one re-checked out via git to restore it.
