I don’t think theres anything wrong with my configuration.nix though.

Not sure if is relevant but I am using flakes and home-manager.

Basic troubleshooting:

  • What command are you running, exactly?
  • Where is your config located?
4

It would be in my /etc/nixos/. I was running sudo nixos-rebuild switch but after trying --flake I’m convinced that my configuration.nix has moved to my /.dotfiles. When I had brought this issue up to a server they had told me it was something wrong with my configuration file. I had told them I was running h-manager and flakes. I’m assuming the only way to go back is to use the command provided in the terminal and reset the path from using the configuration.nix in my /.dotfiles, to the one in my /etc/nixos/ folder?

What do you mean by “moved to your /.dotfiles”?
It’s your config, you decided where it goes, files don’t move on their own.

So depending on where you want it to be located, run sudo nixos-rebuild switch --flake /path/to/your/config.

So when I followed a guide to making flakes I didn’t fully understand that the method being shown by copying the configuration and hardware config to the .dotfiles was also changing the path of the my rebuilds. I assumed it was merely a precautionary backup as that’s what I do normally any time I make changes. I know I don’t exactly have to do that with nixos but It’s a habit I like to keep. I thought that the configs in /etc/nixos/ were always referenced there and couldn’t exactly be put somewhere else. I don’t know if I’m explaining that well. Thank you for helping me to understand that.
