Usage

Real-hardware installation

  • Follow the official NixOS installation guide until NixOS Installation section
  • Clone this repo: git clone https://github.com/mrtnvgr/systems
  • Create your host (look in flake.nix and hosts for examples)
    • Copy /mnt/etc/nixos/hardware-configuration.nix to hardware.nix
  • Install: nixos-install --root /mnt --flake .#<YOUR-HOST-NAME>
  • Move this repo to installed system: mv .systems /mnt/home/<your-username>/
  • Reboot: reboot

Portable environment

Pick a format

  • isoplus - LiveISO, heavily compressed, loaded into the RAM for performance
    • For persistence support, specify --special-arg persistence 1 while creating the image
  • rawplus - full mutability, image of a regular installation
    • Expect a horrible experience on USB sticks
    • Consider only for external SSD/HDD drives
    • Specify --disk-size <MEGABYTES> while creating the image

Steps

  • Bring nixos-generators into the scope: nix shell github:nix-community/nixos-generators
  • Use the minix host or create your own
  • Generate an image: nixos-generate --flake .#<YOUR-HOST-NAME> --format-path genfmts/<FORMAT>.nix
  • Flash: cat <path-to-image> > /dev/sdX
  • Only for isoplus with persistence:
    • Create a new volume: fdisk /dev/sdX <<<$'n\np\n\n\n\nw'
    • Format the volume: mkfs.ext4 -L <YOUR-HOST-NAME>persistence /dev/sdX3

Troubleshooting
