saturnOS

this is the basis of the saturnOS operating system ( sorry guix enjoyers )

to check for syntax errors, run nix repl replEval.nix and once inside the repl, run imported to check for syntax errors

Setup for not nixos

Install nix on your system following the instructions here: https://nixos.org/download.html

Add the nixos 22.11 channel to your system, since we're basing on the latest stable branch for now. nix-channel --add https://nixos.org/channels/nixos-22.11 nixos

Enable flakes, as we're using a flake for our build process.

mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf

Building and Running

We are using the nixos-generators package to help coordinate builds.

VM

To build the VM: nix run github:nix-community/nixos-generators -- -c default.nix -f vm -o result/vm This will build the VM, and register the result in the result/vm symlink.

To run the VM, use sudo result/vm/bin/run-qemu-vm. (sudo can probably be avoided if you are in the KVM group... I think. TODO Lambda look this up)

You can combine the two steps with the following: sudo $(nix run github:nix-community/nixos-generators -- -c default.nix -f vm -o result/vm)

Or to build and run without registering a link (Good if you want a throw away VM which can be garbage collected): sudo $(nix run github:nix-community/nixos-generators -- -c default.nix -f vm)
