Ok, when I googled it earlier I saw "containers and roll back to previous version" and I made a note to do more reading
Your write up was good, much clearer than what's on fedora and Wikipedia. And the fact you pitched immutable OS's in general first caught my attention... The concept is a no brainer. Decouple the os and the rest of the software, and don't bother digging into one of a kind conflicts when updating things - just make it rebuildable and create it fresh. You never know when the wrong bit will flip
Nix's "learn this one thing, configure it once, and you're done" stuck in my head. And after a different distros, a couple lines installed Nvidia, Nvidia's docker package and docker
But then I had to configure WiFi and spend half an hour learning why I couldn't mount an external drive and how to manage it... I still have no regrets, I've got a USB that should start converting my friends and family's old PCs into a self organizing AI/self hosting cluster... Hopefully it works next month lol
But not what I want in a daily driver. I want something that'll quickly do what I tell it and gracefully handle the fact I have 6 versions of Java and no idea why I need a version from 2018 specifically. And that I'm going to add a repo to install something and instantly forget what I did if it seems like the best path forward at the time
You've sold that pretty well - my takeaway was that atomic fedora is very modular and low side effect and also an interchangable foundation I can swap out and roll back easily... At this point, if it can run containers and the drivers I need, it sounds like a great option.
I used to use VMs so every 6-12 months I could start clean with the latest and run setup scripts for my dependencies... It was just easier than debugging some conflict. This sounds even cleaner - I swap out the base at will, and the stuff I've built on it should stay intact. Plus it sounds much more testable
So my main concern is will it run on an HP omen - it has zero Linux support and a bunch of concerning driver needs, but it does have a second m2 slot... What's the worst that can happen? Except apparently some models forget they have fans in Linux and I just know the iGPU-GPU switch will cause some problem with sleeping... But Windows is only going to get worse
Now that you've convinced me this might be the best course (I only see less problems than other distros would have), and I've talked myself into giving it a go, is there any recommended reading or key concepts I should look into? Any particular flavor(s) you'd point me to first?
