My NixOS-configuration

For personal use, but feel free to use it for inspiration.

First installation on NixOS

git clone this repo into /etc/nixos/. After building and creating a user, remember to sudo chown -R USER: the nixos folder, so the git repo doesn't require sudo-privileges.

How to set up /etc/nixos/ folder as a git repo, that can be pushed.

Souce: https://www.youtube.com/watch?v=20BN4gqHwaQ

1. Configure git username/email (in home-manager)

2. Configure SSH: Either copy existing private and public ssh-key to .ssh and add the public SSH-key to user.users.<username>.openssh.authorizedKeys.keys = [] in configuration.nix, or create a new key with ssh-keygen, and add the public key to Github (or what else you are using).

3. Make .git folder: sudo mkdir .git in /etc/nixos

4. Remove sudo requirement: sudo chown <user-name>:users .git (replace <user-name> with the system's username).

5. Run git init.

6. Add progams.git.extraConfig.safe.directory = "/etc/nixos"; in home-manager.

7. Make an empty repo (on Github, or another site).

8. git remote add <remote-name> <link-to-repo> Note1: <remote-name> is often origin, but it can be more descriptive, like github. Note2: If using SSH on Github, <link-to-repo> is of the form [email protected]:<github-username>/<git-repo-name>.git.

9. git push <remote-name> main, and you're done!

Alternative git push <remote-name> master, (github-syntax)and you're done!

• Optional: Add programs.git.extraConfig.init.defaultBranch = "main"; to home-manager.

Alternative: Add programs.git.extraConfig.init.defaultBranch = "master"; to home-manager.

Potential errors

'Git tree ... is dirty'

Make sure to add (and commit) everything to the git repo, and it should be fine. Comes up when you import a file (in configuration.nix, or likewise), but the file is not added to your git repo. Is to make sure, that there are no errors when cloning the repo, and building from it.
