NixOS / Home-Manager / Flake

🔧 Installation

1. Download iso

   # Yoink nixos-unstable
   wget -O nixos.iso https://channels.nixos.org/nixos-unstable/latest-nixos-minimal-x86_64-linux.iso
   
   # Write it to a flash drive
   cp nixos.iso /dev/sdX

2. Boot into the installer.

3. Switch to root user: sudo su -

4. Partitioning

   We create a 512MB EFI boot partition (/dev/nvme0n1p1) and the rest will be our LUKS encrypted physical volume for LVM (/dev/nvme0n1p2).

   $ gdisk /dev/nvme0n1

   • o (create new empty partition table)
   • n (add partition, 512M, type ef00 EFI)
   • n (add partition, remaining space, type 8e00 Linux LVM)
   • w (write partition table and exit)

   Setup the encrypted LUKS partition and open it:

   $ cryptsetup luksFormat /dev/nvme0n1p2
   $ cryptsetup config /dev/nvme0n1p2 --label cryptroot
   $ cryptsetup luksOpen /dev/nvme0n1p2 enc-pv

   We create two logical volumes, a 24GB swap parition and the rest will be our root filesystem

   $ pvcreate /dev/mapper/enc-pv
   $ vgcreate vg /dev/mapper/enc-pv
   $ lvcreate -L 24G -n swap vg
   $ lvcreate -l '100%FREE' -n root vg

   Format partitions

   $ mkfs.fat -F 32 -n boot /dev/nvme0n1p1
   $ mkswap -L swap /dev/vg/swap
   $ swapon /dev/vg/swap
   $ mkfs.btrfs -L root /dev/vg/root

   Mount partitions

   $ mount -t btrfs /dev/vg/root /mnt
   
   # Create the subvolumes
   $ btrfs subvolume create /mnt/root
   $ btrfs subvolume create /mnt/home
   $ btrfs subvolume create /mnt/nix
   $ btrfs subvolume create /mnt/log
   $ umount /mnt
   
   # Mount the directories
   $ mount -o subvol=root,compress=zstd,noatime,ssd,space_cache=v2 /dev/vg/root /mnt
   $ mkdir -p /mnt/{home,nix,var/log}
   $ mount -o subvol=home,compress=zstd,noatime,ssd,space_cache=v2 /dev/vg/root /mnt/home
   $ mount -o subvol=nix,compress=zstd,noatime,ssd,space_cache=v2 /dev/vg/root /mnt/nix
   $ mount -o subvol=log,compress=zstd,noatime,ssd,space_cache=v2 /dev/vg/root /mnt/var/log
   
   # Mount boot partition
   $ mkdir /mnt/boot
   $ mount /dev/nvme0n1p1 /mnt/boot

5. Enable flakes

   $ nix-shell -p nixFlakes

6. Install nixos from flake

   $ nixos-install --flake github:rxyhn/dotfiles#lenovo --impure
