I’ve been curious about NixOS for quite some time. Reading about it I couldn’t see how the config sharing capabilities, setup, or rollabck would be better than Arch and sharing the list of installed packages, using downgrade or chroot.
So I decided to run NixOS in a VM and I’m still confused. An advantage I can see for NixOS is its better use of cores and parallel processing for packages install.
It’s clear that I’m missing something so please help me understand what it is.
Edit: Thank you to everyone in this great community! It’s always so nice to have a constructive and sane discussion.
After reading so many comments, they all confirm what I’ve read before and I may realize that my real problem is already having a stable system and no need for the great NixOS options that are very neat but would not benefit my specific and simplistic needs.
That being said I can’t refrain myself from being curious and will continue testing NixOS.
The need for only 2 config files is the top of the iceberg but hiding more complex configuration to rely on. Not that I really have too much spare time but I do enjoy learning and tweaking NixOS. With its current development state, things are changing a lot so it can keep me busy for months. That’s probably what I was mostly looking for: another toy to play with.
Along my journey I will learn a lot about NixOS and may find a feature that will motivate my switch to it. Thanks again for all your precious feedback!
I’ll also take this opportunity to share the best help I’ve found so far to start with NixOS: https://github.com/MatthiasBenaets/nixos-config And his 3 hours (!) video: https://m.youtube.com/watch?v=AGVXJ-TIv3Y
Right, I totally agree. If I would have to deploy my config on several machines or create dedicated config using a common base then I would have been convinced. I’m still not convinced from a dummy single user point of view but I still believe in this distro and like its approach so I’ll continue experimenting with it and we’ll see where my journey leads me.
At least for now I’m glad to have a new toy I can mess up with. With my Arch system I was getting this weird feeling where I was happy to have an efficient and stable machine while at the same time being bored to have nothing to test/tweak/destroy and rebuild. I mean I love to learn and discover new things so I experiment a bunch of applications and parameters I will never need anyway but it becomes harder and harder to find something that keeps me entertained for more than a day.
I hear you. My openSUSE Leap has been so stable that I got bored with nothing to tweak. Their MicroOS has an immutable system with config file setup capability, and sombody built this for it to make config file creation simple https://opensuse.github.io/fuel-ignition/edit so that was fun for a while. But NixOS was a nice distraction also
