Hi,
I just took the leap an installed NixOS for the appealing
configuration possibilities it offers. For now I don’t quite understand everything (actually quite nothing…) and as a first training, I want to build my system with all my preferred tools and configurations in a way I can reproduce it easily just by cloning a repo and rebuilding from the dotfiles that are inside.
As a lot of peoples on the net, I first thought to symlink a configuration.nix to the /etc/nixos folder in order to keep everything at the same place, but then I read some threads explaining that using the NIX_PATH variable is a cleaner way of doing it.
As this documentation says, I just have to use the nix.nixPath config option to tell nix where is my configuration.
Here is what I wrote:
nix.nixPath = [ "nixos-config=${config.users.users.jm445.home}/.sharedUtils/Nix/dotfiles/configuration.nix" ];
Then I moved my configuration.nix to the right place and rebuilt with sudo nixos-rebuild switch -I nixos-config=./configuration.nix
(from the right place) and the build succeed.
Unfortunately now I can’t rebuild anymore because the NIX_PATH of my root user only contains the line I wrote in the config.
What is the right way to replace only the nixos-config part of the NIX_PATH, without changing the rest of it ?
Thank’s,
JM445
PS: I know I could use flakes to achieve the same thing, but I don’t feel confident enough for now to jump into flakes.
