I don't need a declarative operating system for my home server... but it would be fun...

Yeah, especially after discovering microvm.nix [1] I'm tempted to switch from Proxmox to NixOS.

Edit: The VMs/LXCs are declared with Nix anyway.

What have you done to me, I'm in this position myself too because of the picture.

I'm late to the Nix party. I do the bare minimum just for my at home media server. I guess it's a good time to get caught up on my Linux knowledge again.

disko + nix + home-manager. It feels like magic when the OS comes up from zero to exactly how you left it in two commands. From partition scheme and system configuration, to user configuration.

And it's so easy to change out any system component to whatever you need or bring up a complex service with a little bit of nix config.

I recently moved from Arch to NixOS. It's more fun than I thought it would be.

I am in the same position too. I mean, the appeal is having a config to redo everything if something goes wrong. Unlikely a debian/arch machines that I setup that I had no idea how I got there and what I can or can't install/uninstall, lmao.

This idea has crossed my mind many times. Thankfully, I'm too lazy to do anything about it.

Nix is really cool to me but I can't get all benefits of using it so I'm sticking to Arch based distros.
