@ -5,6 +5,12 @@ Contains my configurations for the software I use.
I'm looking to move forward to configuration with NixOS, but until I get
a bit more experiment on NixOS, I'll keep this repository as simple as possible.
## Nix
Monorepo that contains my commonly used personal environments.
I hope to incorporate my configs at [gh:pegasust/dotfiles](https://github.com/pegasust/dotfiles)
onto this repo for quick env setup (especially devel) on new machines.
## How do I apply these config
- I will always first clone this repository, preferably from local source before

NixOS on WSL<br />

</h1>
A minimal root filesystem for running NixOS on WSL. It can be used with
[DistroLauncher](https://github.com/microsoft/WSL-DistroLauncher) as
`install.tar.gz` or as input to `wsl --import --version 2`.
## Quick start
First, [download the latest release\'s installer](https://github.com/nix-community/NixOS-WSL/releases/latest).
Then open up a Terminal, PowerShell or Command Prompt and run:
```sh
wsl --import NixOS .\NixOS\ nixos-wsl-installer.tar.gz --version 2
```
This sets up a new WSL distribution `NixOS` that is installed under
`.\NixOS`. `nixos-wsl-installer.tar.gz` is the path to the file you
downloaded earlier. You might need to change this path or change to the download directory first.
You can now run NixOS:
```sh
wsl -d NixOS
```
The installer will unpack the file system and subsequently start NixOS.
A few warnings about file systems and locales will pop up. You can
safely ignore them. After systemd has started, you should be greeted
with a bash prompt inside your fresh NixOS installation.
If you want to make NixOS your default distribution, you can do so with
```sh
wsl -s NixOS
```
## Building your own system tarball
This requires access to a system that already has Nix installed. Please refer to the [Nix installation guide](https://nixos.org/guides/install-nix.html) if that\'s not the case.
If you have a flakes-enabled Nix, you can use the following command to
build your own tarball instead of relying on a prebuilt one:
```cmd
nix build github:nix-community/NixOS-WSL#nixosConfigurations.mysystem.config.system.build.installer
```
Or, if you want to build with local changes, run inside your checkout:
```cmd
nix build .#nixosConfigurations.mysystem.config.system.build.installer
```
Without a flakes-enabled Nix, you can build a tarball using:
```cmd
nix-build -A nixosConfigurations.mysystem.config.system.build.installer
```
The resulting installer tarball can then be found under
`./result/tarball/nixos-wsl-installer.tar.gz`.
You can also build a rootfs tarball without wrapping it in the installer
by replacing `installer` with `tarball` in the above commands. The
rootfs tarball can then be found under
`./result/tarball/nixos-wsl-x86_64-linux.tar.gz`.
## Design
Getting NixOS to run under WSL requires some workarounds:
### systemd support
WSL comes with its own (non-substitutable) init system while NixOS uses
systemd. Simply starting systemd later on does not work out of the box,
because systemd as system instance refuses to start if it is not PID 1.
This unfortunate combination is resolved in two ways:
- the user\'s default shell is replaced by a wrapper script that acts
is init system and then drops to the actual shell
- systemd is started in its own PID namespace; therefore, it is PID 1.
The shell wrapper (see above) enters the systemd namespace before
dropping to the shell.
### Installer
Usually WSL distributions ship as a tarball of their root file system.
These tarballs however, can not contain any hard-links due to the way
they are unpacked by WSL, resulting in an \"Unspecified Error\". By
default some Nix-derivations will contain hard-links when they are
built. This results in system tarballs that can not be imported into
WSL. To circumvent this problem, the rootfs tarball is wrapped in that
of a minimal distribution (the installer), that is packaged without any
hard-links. When the installer system is started for the first time, it
overwrites itself with the contents of the rootfs tarball.
