Installing

Fresh system (nixos USB drive)

1. Open a nix-shell with git (if not installed):

   nix-shell -p git

2. Clone the flake

   git clone https://git.samfelag.xyz/marc/samfelag.git

3. Partition the disk We'll partition the disk in the follwing way:

   • 512MB at the beginning for the boot partition
   • 8GB at the end for swap
   • The rest (at the middle) for the filesystem (/)

   1. Locate the disk

      lsblk

   2. Create a GPT partition table

      sudo parted /dev/nvme0n1 -- mklabel gpt

   3. Create the root partition

      sudo parted /dev/nvme0n1 -- mkpart primary 512MB -8GB

   4. Create the swap partition

      sudo parted /dev/nvme0n1 -- mkpart primary linux-swap -8GB 100%

   5. Create the boot partition

      sudo parted /dev/nvme0n1 -- mkpart ESP fat32 1MB 512MB
      sudo parted /dev/nvme0n1 -- set 3 esp on

4. Format the partitions

   1. Root partition

      sudo mkfs.ext4 -L nixos /dev/nvme0n1p1

   2. Swap partition

      sudo mkswap -L swap /dev/nvme0n1p2

   3. Boot partition

      sudo mkfs.fat -F 32 -n BOOT /dev/nvme0n1p3

5. Mount the filesystems

   1. Root partition

      sudo mount /dev/disk/by-label/nixos /mnt

   2. Boot partition

      sudo mkdir -p /mnt/boot
      sudo mount /dev/disk/by-label/BOOT /mnt/boot

   3. Swap partition (if needed)

      sudo swapon /dev/disk/by-label/swap

6. Create the host nix configuration If the host is not present under system/hosts, create a new folder for the host. Generate the hardware configuration file, you can use nixos-generate-config as a base:

   nixos-generate-config --dir <<host directory>> --no-filesystems

7. Install nixos!

   sudo nixos-install --impure --root /mnt --flake '.#reykjavik'

8. Set up the user You'll set the root password during the installation. You can then reboot and use the installed OS. First thing you'll have to do is log in as root and set the password for your user:

   passwd marc

Fresh system (vultr)

1. [Optional] Set the root password via the Vultr Console, so you can ssh to the instance

2. Open a nix-shell with git (if not installed):

   nix-shell -p git

3. Clone the flake

   git clone https://git.samfelag.xyz/marc/samfelag.git

4. Partition the disk We'll partition the disk in the follwing way:

   • 512MB at the beginning for the boot partition
   • 8GB at the end for swap
   • The rest (at the middle) for the filesystem (/)

   • Locate the disk

     lsblk

   • Create a MBR partition table

     sudo parted /dev/vda -- mklabel msdos

   • Create the root partition

     sudo parted /dev/vda -- mkpart primary 1MiB -8GiB

   • Create the swap partition

     sudo parted /dev/vda -- mkpart primary linux-swap -8GiB 100%

   • Create the boot partition

     sudo parted /dev/vda -- mkpart ESP fat32 1MB 512MB
     sudo parted /dev/vda -- set 3 esp on

5. Format the partitions

   1. Root partition

      sudo mkfs.ext4 -L nixos /dev/vda1

   2. Swap partition

      sudo mkswap -L swap /dev/vda2

6. Mount the filesystems

   1. Root partition

      sudo mount /dev/disk/by-label/nixos /mnt

   2. Swap partition (if needed)

      sudo swapon /dev/disk/by-label/swap

7. Create the host nix configuration If the host is not present under system/hosts, create a new folder for the host. Generate the hardware configuration file, you can use nixos-generate-config as a base:

   nixos-generate-config --dir <<host directory>> --no-filesystems

8. Install nixos!

   sudo nixos-install --impure --root /mnt --flake '.#vultr-test'

9. Set up the user You'll set the root password during the installation. You can then reboot and use the installed OS. First thing you'll have to do is log in as root and set the password for your user:

   passwd marc

Rebuilding

sudo nixos-rebuild switch --impure --flake '.#reykjavik'

Themeing

We use nix-colors to (try to) keep a consistent theme across all applications. This uses base-16 themes (here is a styiling guide for it).
