Rebuild nixos and points to dotfiles dir:
|
||
|
||
```
|
||
sudo nixos-rebuild switch --flake ~/dotfiles/nixos#macbookair
|
||
# or
|
||
sudo nixos-rebuild switch --flake ~/dotfiles/nixos#wsl
|
||
# or (macOS)
|
||
sudo -H nix run github:lnl7/nix-darwin -- switch --flake ~/dotfiles/nixos#Daniel-Macbook-Air
|
||
```
|
||
|
||
## Server (nixos-server)
|
||
|
||
One-time on the server (git is not installed until after the first rebuild, so use nix run to get git):
|
||
|
||
```bash
|
||
nix run --extra-experimental-features "nix-command flakes" nixpkgs#git -- clone https://github.com/DannyDannyDanny/dotfiles.git /tmp/dotfiles
|
||
sudo mv /tmp/dotfiles /etc/dotfiles
|
||
# Enable flakes for this run (needed if the current system config does not)
|
||
sudo nixos-rebuild switch --flake /etc/dotfiles/nixos#nixos-server --option accept-flake-config true
|
||
```
|
||
If that fails with "does not provide attribute ... nixos-rebuild", enable flakes for the Nix daemon via the current config (on NixOS, `/etc/nix/nix.conf` is often read-only), then build and switch manually.
|
||
|
||
**From your Mac:** push a config that enables flakes, then on the server copy it and rebuild:
|
||
```bash
|
||
scp nixos/server-configuration-with-flakes.nix danny@<server>:/tmp/configuration.nix
|
||
```
|
||
**On the server:**
|
||
```bash
|
||
sudo cp /tmp/configuration.nix /etc/nixos/configuration.nix
|
||
sudo nixos-rebuild switch
|
||
```
|
||
Then build and switch to the flake:
|
||
```bash
|
||
sudo nix build /etc/dotfiles/nixos#nixosConfigurations.nixos-server.config.system.build.toplevel -o /tmp/nixos-result
|
||
sudo /tmp/nixos-result/bin/switch-to-configuration switch
|
||
```
|
||
|
||
Use `git@github.com:DannyDannyDanny/dotfiles.git` if the repo is private (clone as danny then `sudo mv` and `sudo chown -R root:root /etc/dotfiles`).
|
||
|
||
SSH keys for danny (not in repo): from your machine `scp ~/.ssh/*.pub danny@server:/tmp/`, then on server `mkdir -p ~/.ssh; cat /tmp/*.pub >> ~/.ssh/authorized_keys`.
|
||
|
||
After that, a timer pulls and rebuilds every 15 min when `main` changes. Config lives in `hosts/nixos-server.nix` and `hosts/nixos-server-hardware.nix`.
|
||
|
||
**Pull when git is not in PATH** (e.g. before first rebuild or when `sudo git` says "command not found"):
|
||
```bash
|
||
sudo nix run nixpkgs#git -- -C /etc/dotfiles pull origin main
|
||
```
|
||
Then run `sudo nixos-rebuild switch --flake /etc/dotfiles/nixos#nixos-server` as usual. After that, git is in the system profile; for manual pulls you can use `sudo /run/current-system/sw/bin/git -C /etc/dotfiles pull origin main` if `sudo git` still isn’t in PATH.
