NixOs Flake setup

This flake setup based on Ruixi-rebirth works. All credit goes to him/her.

Fresh installation. Not dual boot

Prepare and boot into a 64-bit nixos minimal iso image. Currently this is version 23.05

Partitioning the disk

How to install?

Minimal installation (including wm, no tmpfs as root), go to here

How to install ?(root on tmpfs)

Prepare a 64-bit nixos minimal iso image and burn it, then enter the live system. Suppose I have divided two partitions /dev/nvme0n1p1 /dev/nvme0n1p3
Format the partition

  mkfs.fat -F 32 /dev/nvme0n1p1
  mkfs.ext4 /dev/nvme0n1p3

Mount

  mount -t tmpfs none /mnt
  mkdir -p /mnt/{boot,nix,etc/nixos}
  mount /dev/nvme0n1p3 /mnt/nix
  mount /dev/nvme0n1p1 /mnt/boot
  mkdir -p /mnt/nix/persist/etc/nixos
  mount -o bind /mnt/nix/persist/etc/nixos /mnt/etc/nixos

Generate a basic configuration

  nixos-generate-config --root /mnt

Clone the repository locally

nix-shell -p git
git clone  https://github.com/Ruixi-rebirth/flakes.git /mnt/etc/nixos/Flakes
cd /mnt/etc/nixos/Flakes/
nix develop --extra-experimental-features nix-command --extra-experimental-features flakes

Copy hardware-configuration.nix from /mnt/etc/nixos to /mnt/etc/nixos/Flakes/hosts/laptop/hardware-configuration.nix

cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/Flakes/hosts/laptop/hardware-configuration.nix

Modify the overwritten hardware-configuration.nix

nvim /mnt/etc/nixos/Flakes/hosts/laptop/hardware-configuration.nix

...
#This is just an example
#Please refer to `https://elis.nu/blog/2020/05/nixos-tmpfs-as-root/#step-4-1-configure-disks`

    { device = "none";
      fsType = "tmpfs";

remove '/mnt/etc/nixos/Flakes/.git'

rm -rf .git

Username modification: edit /mnt/etc/nixos/Flakes/flake.nix to modify user variable, hostname modification: edit /mnt/etc/nixos/Flakes/hosts/system.nix to modify* The hostName value in the networking property group
Use the hash password generated by the mkpasswd {PASSWORD} -m sha-512 command to replace the value of users.users.<name>.hashedPassword in /mnt/etc/nixos/Flakes/hosts/laptop/wayland/default.nix ( there is two place needs to be displace )

Perform install

nixos-install --no-root-passwd --flake .#laptop

Reboot

reboot

Enjoy it!

You have to be root to use parted. You can use sudo or sudo su - to become root

# Create partition tables
parted /dev/sdc mklabel gpt # or 'msdos' for legacy boot
parted /dev/sdc -- mkpart primary 512MiB -8GiB # for uefi, 1MiB for msdod
parted /dev/sdc -- mkpart primary linux-swap -8GiB 100% 

# Extra partitions for UEFI
parted /dev/sdc -- mkpart ESP fat32 1Mib 512MiB
parted /dev/sdc -- set 3 esp on

# Create the filesystems
mkfs.ext4 -L nixos /dev/sdc1
mkswap -L swap /dev/sdc2
# extra for UEFI 
mkfs.fat -F 32 -n boot /dev/sdc3

Mounting the drives

# Mount the partitions
mount /dev/disk/by-label/nixos /mnt

# Extra for UEFI */
mkdir -p /mnt/boot
mount /dev/disk/by-label/boot /mnt/boot

# Switch the swap on
swapon /dev/sdc2

Generate basic NixOS configuration files

nixos-generate-config --root /mnt

Clone and install NixOS via flake.

# Start a new shell with git
nix-shell -p git
git clone https://github.com/fodurrr/nixos-flake.git /mnt/etc/nixos/Flakes 

cd /mnt/etc/nixos/Flakes/

# Start a new environment with flakes
nix develop --extra-experimental-features nix-command --extra-experimental-features flakes 

cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/Flakes/hosts/laptop/hardware-configuration.nix

nixos-install --no-root-passwd --flake .#laptop

reboot

Enjoy it!

Simple clone and update if you have already installed it before.

nix-shell -p git

git clone https://github.com/fodurrr/nixos-flake.git

cd nixos-flake

# nix develop --extra-experimental-features nix-command --extra-experimental-features flakes

# nix flake update # Update flake lock

sudo nixos-rebuild switch --flake .#laptop
