that, using a 20+-year-old technology (RPM).

Specifically, the problem with TensorFlow is that it wants to download its 
dependencies when you compile it, then compile them at the same time. That 
can't work because the build servers don't have internet connectivity.

I was replying to the message saying that Bazel would be a good choice by 
relating our experience.

You brought Kata Containers up. If you use containers on Linux and you care

virtual machine hypervisor functionality to make sure the code in the 
container can't break out of the container, without making a full virtual
