This repository contains my NixOS configurations

Warning

Work in progress, expect bugs and regressions

Hosts

Desktops

• nixie - daily driver laptop
• thlix - minimal personal desktop
• minix - base of all desktops (ISO builds)

Servers

• cloud - main server

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
