Nix Config

A personal Nix configuration across my computers running Nix and NixOS.

NixOS Live Media

• Nix needs to be installed
• Build an ISO by running the following command

nix build .#ISO --extra-experimental-features "nix-command flakes" --verbose --print-build-logs

• Resulting ISO will be in the ./result/iso

NixOS installation

• Load into the NixOS Live Installation Image
• Clone and enter the repo using git clone
• If using disko¹, setup disks using

sudo nix run github:nix-community/disko --extra-experimental-features "nix-command flakes" -- --mode disko hosts/{hostname}/disko.nix

• Set a password for the nixos account using passwd nixos
• Copy the sops-nix age key file using sftp to the specified location
• Install with sudo nixos-install --no-root-passwd --no-channel-copy --flake github:CollinDewey/nix-config#{hostname}²

Displaylink

For BURGUNDY, the displaylink driver is downloaded using this command

nix-prefetch-url --name displaylink-580.zip https://www.synaptics.com/sites/default/files/exe_files/2023-08/DisplayLink%20USB%20Graphics%20Software%20for%20Ubuntu5.8-EXE.zip

Footnotes

1. Disko actually has flake support which would let me avoid needing to clone the repo, but I couldn't get it working ↩

2. If using / on tmpfs, nixos-install creates a temporary directory for building. If you get an error from nixos-install about running out of space, give tmpfs more space. For example, mount -o remount,size=8G /mnt ↩
