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

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

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
```
Restart current shell to load Nix as a PATH
```
bash
```

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

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
```
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

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 - https://github.com/NixOS/nixpkgs/issues/138423
```
sudo apt-get install --assume-yes uidmap
```

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

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

Install WSL2 with default Ubuntu. Activate home-manager as kachick@wsl-ubuntu
Install NixOS-WSL. Activate home-manager with $(whoami)@wsl-nixos
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.

Apply home-manager with kachick@macbook for minimum packages.
Install some packages without Nix
Use Lima for development tasks.

Lima

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

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.
