nix-config

In this repository I keep my flake based nixos and home-manager configurations. Next to that, there is a configuration to build live-cds.

NixOS

Home-manager runs as a NixOS module, so a single rebuild applies both system and user configuration.

sudo nixos-rebuild --flake . switch

Or using the justfile shorthand:

just switch

Live cd

Ran from the root of this repo.

nix build .#nixosConfigurations.baseIso.config.system.build.isoImage

After a successful build, the iso can be found in result/iso/. Use cp to copy the image to for instance an usb thumb drive.

sudo cp result/iso/nixos-minimal-25.05.20250525.7c43f08-x86_64-linux.iso /dev/sdb

Don't forget to replace the destination drive with the proper drive.

Remote install with nix anywhere

The live iso contains ssh public keys, has sshd running and contains nmtui to setup the network. Once the network is up, use nixos-anywhere to install the system:

nix run github:nix-community/nixos-anywhere -- --flake .#${TARGET_HOST} --generate-hardware-config nixos-generate-config hosts/${TARGET_HOST}/hardware-configuration.nix --target-host root@${TARGET_HOST_IP}

Desktop environments

One desktop is supported via settings.gui: plasma.

Laptop power policy

Battery charge thresholds are managed in BIOS/firmware (vendor power settings), not in NixOS services.

This keeps charging behavior consistent regardless of OS state. Desktop session power behavior remains handled by Plasma.
