Been daily for a while now, came over from Garuda, and a few other Arch derivative before that. NixOS is 99.9% fantastic. Lenovo carbon X1 Gen 6. Runs great. Newer custom build higher end desktop with AMD 7900RX GPU. Also runs great. I have a feeling it’ll run great on pretty much anything.

The package store is amazing. The package store absolutely dwarfs the AUR. That being said, it seems a lot of the store packages are support / dependency packages that you wouldn’t install standalone.
I always had a concern in the back of my mind with the AUR. Is the package trusted by multiple people?
I’ve not had to rollback much, but it’s SUPER simple, and takes seconds for the most part. A reboot at the most.

Things I wish I knew: I run declarative for everything, rather than imperative. Therefore, small changes are a tiny bit more of a hassle. Example: changing the hosts file. Rather than a quick hosts file edit and done, it’s a quick edit of the system configuration file, then a nixos-rebuild switch. Nearly any change is like this. (I’ve not moved to flakes yet.)

if you have any shell scripts, and they’re hard-coded to the env: #!/bin/bash, #!/usr/bin/zsh, etc… you’ll need to port those over to #!/usr/bin/env

appimages are well supported, but I ran into an issue where a custom appimage that someone else wrote won’t authenticate correctly because the browser isn’t included in the environment. I could t-shoot it more, but just too damn lazy to care.

The local storage location for apps can get huge rather quickly, as each iteration/change is stored for rollback purposes. Make sure to setup a garbage collection schedule with whatever your comfortable with.

Would i recommend? Depends on your patience and prior experience. NixOs is VERY VERY different than arch or pretty much any other distro, even other immutable ones. It takes a bit to get your head wrapped around it.

I saw someone say start with Nix (the package manager) on your current distro, learn the ropes, add in pieces like Flakes and Home Manager as you learn. Learn the Nix language. And then move to NixOS. Probably good advice.

I ignored all of that. Jumped in head first. Lots of frustration in the beginning. But now… I won’t be going back to a standard linux distro.

Immutability makes me warm and fuzzy. Being absolutely sure that I can easily recover from a boneheaded mistake. Beautiful. Hard drive shits the bed? Drop in a new one, apply my configs, and I’m right back where I was within 30 minutes, complete with all data, apps installed and configured? Priceless.
