The app-emulation/nvidia-container-runtime package is a huge pain to maintain, since it has a complex in-container build process, and even worse is written in Go. It's possible to try to use a pre-built version for a binary OS (like RHEL) but this isn't a great option either.

However, it turns out that nvidia-container-runtime is a really trivial program that would probably take me 30 minutes to rewrite in python:

Therefore, it may make sense just to maintain a fork of this program in python to avoid the over-engineered build process for this dumb utility.
