We are reinventing the wheel in some things, but in this we're not. We're 
simply trying to make an RPM .spec file that builds the latest version of 
TensorFlow. There are at least a dozen other distributions who need to do 
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 
about security, you should take a look at it. It's about using the processor's 
virtual machine hypervisor functionality to make sure the code in the 
container can't break out of the container, without making a full virtual 
machine.
