Due to the still early development of NixOS, Home manager is in some ways very similar to nix-env and flakes is still highly experimental. Also, the configuration parameters are changing quite significantly with the distro development. I’m sure this will all settle down when the distro will become more mature but to be honest that’s also what attracts me. I like chaos ^^ Seriously, this shows me some potential for great achievements. I will continue testing NixOS but for now I didn’t find THE reason to leave Arch yet. 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. Will see where my journey leads me.
