Loading

For visitors

If you are using Podman, you can test the pre-built ubuntu container-image as follows.

bash <(curl -fsSL https://raw.githubusercontent.com/kachick/dotfiles/main/containers/sandbox-with-ghcr.bash) latest

Or, you can directly use some commands with nix run without any installation steps.

nix run 'github:kachick/dotfiles#todo'

List them

nix flake show 'github:kachick/dotfiles' --json 2>/dev/null | jq '.packages | ."x86_64-linux" | to_entries | map("\(.key) # \(.value.description)")'

NixOS

List defined hostnames

nix eval --json 'github:kachick/dotfiles#nixosConfigurations' --apply 'builtins.attrNames' | jq '.[]'

Using flake style is disabled in NixOS by default and you should inject git command to use flakes.

NOTICE: This command might drop all existing users except which defined in configurations.

nix --extra-experimental-features 'nix-command flakes' shell 'github:NixOS/nixpkgs/nixos-25.11#gitMinimal' \
  --command sudo nixos-rebuild switch \
  --flake "github:kachick/dotfiles#$(hostname)" \
  --show-trace

Finally, reboot the device

sudo reboot now

Refer to the sample flake for an example of inheriting modules from another repository.

home-manager

List definitions

nix eval --json 'github:kachick/dotfiles#homeConfigurations' --apply 'builtins.attrNames' | jq '.[]'

Ubuntu

1. Install Nix and enable Flakes

   extra_conf_path="$(mktemp --suffix=.extra.nix.conf)"
   echo 'experimental-features = nix-command flakes' >> "$extra_conf_path"
   echo "trusted-users = root $USER @wheel" >> "$extra_conf_path"
   
   sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install) --daemon --nix-extra-conf-file "$extra_conf_path"

2. If you forgot something adding in the installation phase, manually add it.
   Some config needs rebooting to apply it such as trusted-users.

   echo 'experimental-features = nix-command flakes' | sudo tee --append /etc/nix/nix.conf

3. Make sure there is a nix directory that is used in the home-manager.
   This is a workaround, See the thread for detail

   mkdir -p ~/.local/state/nix/profiles

4. Restart current shell to load Nix as a PATH

   bash

5. Apply dotfiles

   nix run 'github:kachick/dotfiles#home-manager' -- switch -b backup --flake 'github:kachick/dotfiles#wsl-ubuntu'

6. Apply system level dotfiles with sudo for nix command

   sudoc nix run 'github:kachick/dotfiles#apply-system'

7. Enable tailscale ssh if required

   sudoc tailscale up --ssh

Podman on Ubuntu

1. Install uidmap without Nix for use of podman even if the podman will be installed from nixpkgs

   • "shadow" in nixpkg is not enough for podman - NixOS/nixpkgs#138423

   sudo apt-get install --assume-yes uidmap

2. Make sure the cgroup v1 is disabled if you on WSL, See the docs

3. Make sure you can run containers as podman run public.ecr.aws/debian/debian:stable-slim cat /etc/os-release

Debian

After installing missing tools, you can complete same steps as Ubuntu

sudo apt update
sudo apt upgrade
sudo apt install --assume-yes curl
sudo apt install --assume-yes dbus-user-session # For podman

Remember to set special config and reboot if you on WSL

echo '
[boot]
systemd=true' | sudo tee /etc/wsl.conf

Windows

1. Install WSL2 with default Ubuntu. Activate home-manager as kachick@wsl-ubuntu
2. Install NixOS-WSL. Activate home-manager with $(whoami)@wsl-nixos
3. Adjust Windows experience as written in extracted steps and as written in CI for further detail.

Multi-booting on Windows and Linux

Check traps

Windows on Linux

Use winboat.
The full-desktop feature is powered-by FreeRDP.
You can exit the full-screen RDP session with Ctrl + Alt + Enter. (Not the End or Pause/Break keys)

macOS

I basically give up to maintain my old Intel Mac.
However I should keep the minimum environment for now.

1. Make sure installing official Nix. Determinate Nix dropped x86_64-darwin. It is earlier than nixpkgs.
2. Apply home-manager with kachick@macbook for minimum packages.
3. Install some packages without Nix
4. Use Lima for development tasks.

Lima

1. Setup Lima with default Ubuntu guest
2. In the lima as limactl start, apply home-manager with kachick@lima
3. You can run containers as lima nerdctl run --rm hello-world. You can also use podman after above Podman on Ubuntu setups

Shorthand

If you are developing this repository, putting .env makes easy reactivations.

echo 'HM_HOST_SLUG=wsl-ubuntu' > .env

Then you can enable configurations with

task apply
