>> in decades there will a vocal contingent of people lamenting the fact that we all run immutable Microsoft Kubernetes Ubuntu (MSKU) instead of using the more refined NixOS approach.

You are, unfortunately, correct. Some of us still run illumos Unix (SmartOS), but we are a tiny minority. I hope that things can work out so that something other than the lowest common denominator is accessible enough to also have a pervasive footprint.

A lot of very crummy ideas are popular in ways that would not have been imaginable 15 years ago.

>> or even an unsophisticated approach like a Dockerfile

In a handful of "higher end" on the salary side of DevOps/SRE roles I have done, I managed to quietly do things with flake.nix -- next time around I'll do them with Guix. I can get Guix container images going, that's not hard for me.

But yeah, doing things non-Docker isn't too hard for us DevOps ninjas (what DevOps was in 2012, not the watered down thing today).

After doing flake.nix, I managed to get written company policy ratified by our legal team that all container images must be binary reproducible. That probably fell apart since I left, unless the high quality CTO I was serving is still there.
