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 | jq '.apps | ."x86_64-linux" | keys[]'

NixOS

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

For example

nix --extra-experimental-features 'nix-command flakes' shell 'github:NixOS/nixpkgs/nixos-24.11#git' \
  --command sudo nixos-rebuild switch \
  --flake "github:kachick/dotfiles#$(hostname)" \
  --show-trace
sudo reboot now

List defined hostnames

nix flake show 'github:kachick/dotfiles' --json | jq '.nixosConfigurations | keys[]'

This repository intentionally reverts the home-manager NixOS module.
So, you should activate the user dotfiles with standalone home-manager even though NixOS.

nix run 'github:kachick/dotfiles#home-manager' -- switch -b backup --flake 'github:kachick/dotfiles#kachick@nixos-desktop'

See GH-680 for background

NixOS is often difficult for beginners like me. So I also use Lima for several issues.

Ubuntu

1. Install Nix package manager with DeterminateSystems/nix-installer to enable Flakes by default.

   curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

2. 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

3. Restart current shell to load Nix as a PATH

   bash

4. Apply dotfiles for each use

   nix run 'github:kachick/dotfiles#home-manager' -- switch -b backup --flake 'github:kachick/dotfiles#user@linux-cli'

   Candidates

   • user@linux-cli # Used in container

5. home-manager installed OpenSSH disabled GSSAPI by default.
   So suppress /etc/ssh/ssh_config line 53: Unsupported option "gssapiauthentication" with following command

   sudo chmod -r /etc/ssh/ssh_config

6. If you faced to lcoale errors such as -bash: warning: setlocale: LC_TIME: cannot change locale (en_DK.UTF-8): No such file or directory

   sudo localedef -f UTF-8 -i en_DK en_DK.UTF-8

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 putting /etc/containers/policy.json, it is not a home-manager role

   sudo mkdir -p /etc/containers
   cd /etc/containers
   sudo curl -OL https://raw.githubusercontent.com/kachick/dotfiles/main/config/containers/policy.json

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

4. Make sure you can run containers as podman run public.ecr.aws/debian/debian:12.6-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

macOS

I basically give up to maintain macOS environment.

1. Apply home-manager with kachick@macbook for minimum packages.
2. Install some packages without Nix
3. 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

How to setup secrets

Note

If you are developing this repository, the simple reactivation is as follows.

makers apply 'kachick@wsl-ubuntu'

For NixOS

sudo nixos-rebuild switch --flake ".#$(hostname)" --show-trace && \
    makers apply 'kachick@nixos-desktop'

If you encounter any errors in the above steps, Check and update CI and wiki.
