The software versions would be the same, but the exact files inside VM would be very different, could this be used to fingerprint users? File timestamp could also be used to track different users.
Or is it a better idea to always start with latest VM images and boot into VM live mode, then upgrade system? This won’t work if system need to be restarted to upgrade though.
