Idempotent, deterministic builds are an argument in favor of synthetic virtual machines. Synthetic VMs like the JVM or CLR should, at least insofar as they don't contain native code, execute in a manner largely isolated from the vagaries of minor hardware/OS differences. Not an expert, but native VMs do not and cannot isolate processes from hardware details (e.g. Xen, Virtual Box), or from OS details (e.g. Docker, containerd).
