Setup Instructions

Create a bootable USB drive

  • Download NixOS to $ISO_PATH
  • insert drive
  • lsblk -> find out drive name (e.g. /dev/sdb) $DRIVE
  • run (as sudo) dd bs=4M if=$ISO_PATH of=$DRIVE conv=fdatasync status=progress && sync

Preparing Windows 10 to keep a Bootable Windows Partition

Roughly this https://github.com/andywhite37/nixos/blob/master/DUAL_BOOT_WINDOWS_GUIDE.md

  1. Install all updates
  2. Create a windows recovery USB Drive (Search for "Create Recovery Drive") [Fair warning: This is slooooooooow]
  3. Shrink main Windows partition using built-in Disk Management tool
  4. Use Macrorit Partition Expert to extend EFI partition to 1024MB
  5. (optional) Delete Recovery Partition(s) 1 Install NixOS as below, re-using the existing EFI boot partition setup by Windows, and things should work with systemd-boot out of the box!

Actual installation

Roughly this https://qfpl.io/posts/installing-nixos/

  • sudo -i
  • lsblk -> find out disk name (e.g. /dev/sda) $DISK
  • export DISK=/dev/sda
  • gdisk $DISK
    • p (print)
    • d (delete)
    • n (new)
      • number=1, begin=default, end=+1G, hex code=ef00 (not needed if dual boot) ($BOOT from now on, or /dev/sda1 etc)
      • number=2, begin=default, end=default, hex code=8e00 ($MAIN from now on)
    • w (write)
  • export BOOT=/dev/sda1
  • export MAIN=/dev/sda2
  • encryption
    • cryptsetup luksFormat $MAIN
    • cryptsetup luksOpen $MAIN nixos-enc
    • pvcreate /dev/mapper/nixos-enc
    • vgcreate nixos-vg /dev/mapper/nixos-enc
    • lvcreate -L <swap size, e.g. 8G, usually pick 2xRAM for hibernation if space doesn't matter> -n swap nixos-vg
    • lvcreate -l 100%FREE -n root nixos-vg
  • create fs
    • mkfs.vfat -n boot $BOOT (not needed if dual boot)
    • mkfs.ext4 -L nixos /dev/nixos-vg/root
    • mkswap -L swap /dev/nixos-vg/swap
    • swapon /dev/nixos-vg/swap
  • mount
    • mount /dev/nixos-vg/root /mnt
    • mkdir /mnt/boot
    • mount $BOOT /mnt/boot
  • generate config
    • nixos-generate-config --root /mnt
  • add stuff to config

required:

boot.initrd.luks.devices = {
  root = {
    device = "$MAIN";
    preLVM = true;
  };
};

# If not dual-booting with GRUB
boot.loader.systemd-boot.enable = true;

networking.networkmanager.enable = true;

users.users.farlion = {
  extraGroups = ["wheel" "video" "audio" "disk" "networkmanager"];
  isNormalUser = true;
};
  • nixos go brrrr
    • nixos-install
    • reboot

Enable this setup

($NIXOS_CONFIG is the location of this repo)

  1. change your name to farlion because it's hardcoded in the configurations
  2. passwd farlion and then su
  3. git clone https://github.com/workflow/nixos-config.git $NIXOS_CONFIG
  4. From$NIXOS_CONFIG/machines/*/system.nix as a template, set required settings like the networking.hostname and the correct networking interfaces to enable DHCP
  5. Update flake.nix with new machine (name = hostname)
  6. nix shell nixpkgs#cachix -c cachix use workflow-nixos-config
  7. sudo nixos-rebuild switch --flake $NIXOS_CONFIG#<machine name, empty if hostname> --override-input secrets nixpkgs
  8. Reboot

Post-installation steps

  1. Push any local $NIXOS_CONFIG config changes to github
  2. Remove local $NIXOS_CONFIG and symlink it to ~/code/nixos-config
  3. Go through secret setup instructions / customize system to your needs
  4. Change root passwd
  5. Rerun nh os switch
  6. Reboot
