Frontear's Dotfiles

Declarative and reproducible configuration for my systems, powered by NixOS ❄️.

Installation

1. Build the latest ISO image through Nix:

   $ nix build github:Frontear/dotfiles#ISO-3DT4F02.config.system.build.isoImage

   Then, copy it to a USB drive and boot from it.

2. Create the expected partition table using the following script:

   #!/usr/bin/env bash
   
   # NOTE: run this as root.
   
   # Declare the target disk ahead-of-time
   export DISK="/dev/<DEVICE>" # e.g. /dev/sda, /dev/nvme0n1, ...
   
   # Wipe all existing partitions from the drive
   sfdisk --delete "$DISK"
   
   # Use the GPT partition layout
   sfdisk "$DISK" <<< "label: gpt"
   
   # Create the EFI partition
   sfdisk --append "$DISK" <<< ",1G,U"
   
   # Create the Nix partition
   sfdisk --append "$DISK" <<< ",,L"
   
   # Label the newly created partitions
   sfdisk --part-label "$DISK" 1 "boot"
   sfdisk --part-label "$DISK" 2 "nix"

3. Format the created partitions with the expected fs types:

   $ wipefs --all /dev/disk/by-partlabel/boot
   $ wipefs --all /dev/disk/by-partlabel/nix
   $ mkfs.fat -F 32 /dev/disk/by-partlabel/boot
   $ mkfs.btrfs -n 64k /dev/disk/by-partlabel/nix

4. Mount them into /mnt for the installer:

   $ mount -t tmpfs -o mode=0755,noatime,noswap,size=1G tmpfs /mnt --mkdir
   $ mount -o dmask=0022,fmask=0022,noatime /dev/disk/by-partlabel/boot /mnt/boot --mkdir
   $ mount -o compress=zstd:15,noatime /dev/disk/by-partlabel/nix /mnt/nix --mkdir

5. Install configuration to target root in /mnt:

   $ nixos-install --flake "github:Frontear/dotfiles#<HOST>" --no-channel-copy --no-root-password
