isbl-nixos

Warning

I moved from nixos back to fedora recently. Mostly because Asahi linux works better and I like all my linux to be same. HOWEVER, I still use nixos for my "dotfiles" via home-manager. See my nix-home repo. My server setup can be found at nixos-servers

This repo currently contains my desktop nixos setup.

Getting Started

1. install nixos with user named isabella
2. git clone this repo to ~/nixos (some parts of this config assume this path)
3. ln -s /home/isabella/nixos/flake.nix /etc/nixos/
4. nixos-rebuild switch
5. configure 1password to run on start in Tweaks

Getting Started Asahi

This is long. Click to expand.

(verified working when I was switching from ext4 to btrfs)

1. Boot into the installer. guide
2. Become root sudo -s
3. Delete existing install (if exists)

   sgdisk /dev/nvme0n1 -p
   sgdisk /dev/nvme0n1 -d=X # replace X with old partition, probably 5

4. Connect to internet to get btrfs

iwctl
station list
station wlan0 scan
station wlan0 get-networks
station wlan0 connect NETWORKNAME
# wait for password prompt
exit

or if you know the network name

iwctl
station wlan0 show
station wlan0 connect-hidden NETWORKNAME
# wait for password prompt

5. Create new partition

sgdisk /dev/nvme0n1 -p # to see preexisting partitions
sgdisk /dev/nvme0n1 -n 0:0 -s
sgdisk /dev/nvme0n1 -p # look for the new partition
cryptsetup luksFormat /dev/nvme0n1p5
cryptsetup luksOpen /dev/nvme0n1p5 cryptroot
nix-shell -p btrfs-progs
mkfs.btrfs -L nixos /dev/mapper/cryptroot
mount /dev/mapper/cryptroot /mnt
cd /mnt
btrfs subvolume create nix
btrfs subvolume create rootfs
btrfs subvolume create persistent
cd
umount /mnt

6. Mount everything and copy stuff

mount -o subvol=rootfs /dev/disk/by-label/nixos /mnt
mkdir /mnt/boot /mnt/nix /mnt/persistent
mount -o subvol=nix /dev/disk/by-label/nixos /mnt/nix
mount -o subvol=persistent /dev/disk/by-label/nixos /mnt/persistent
mount /dev/disk/by-partuuid/`cat /proc/device-tree/chosen/asahi,efi-system-partition` /mnt/boot

7. Generate config

nixos-generate-config --root /mnt
cp -r /etc/nixos/apple-silicon-support /mnt/etc/nixos/
chmod -R +w /mnt/etc/nixos/
nano /mnt/etc/nixos/configuration.nix

8. Deal with firmware+flakes

mkdir -p /mnt/etc/nixos/firmware
cp /mnt/boot/asahi/{all_firmware.tar.gz,kernelcache*} /mnt/etc/nixos/firmware
cd /mnt/etc/nixos/firmware
nix-shell -p git
echo "{outputs = {...}:{};}" > flake.nix
git init
git branch -m main
git config user.name "Isabella Skorepova"
git config user.email "isabella@skorepova.info"
git add .
git commit -am "firmware"

9. Change config a bit

imports =
  [
    ./hardware-configuration.nix
    ./apple-silicon-support
  ];

# Use the systemd-boot EFI boot loader.
boot.loader.systemd-boot.enable = true;
boot.loader.efi.canTouchEfiVariables = false;

hardware.asahi.pkgsSystem = "x86_64-linux";
networking.wireless.iwd = {enable=true; settings.General.EnableNetworkConfiguration = true; } ;
hardware.asahi.peripheralFirmwareDirectory = ./firmware;
networking.hostName = "IsblAsahi";
users.users.isabella = {
  isNormalUser = true;
  extraGroups = ["wheel"];
};
nix.settings.experimental-features = [ "nix-command" "flakes" ];
environment.systemPackages = with pkgs; [
  git vim
];

10. Install

systemctl restart systemd-timesyncd
nixos-install
reboot

11. Post-install

• Login as root and passwd isabella
• Login as isabella
• iwctl to connect to WiFi (see previous step)
• git clone https://github.com/CodeWitchBella/nixos
• sudo ln -s /home/isabella/nixos/flake.nix /etc/nixos/
• cp /etc/nixos/hardware-configuration.nix systems/asahi/
• edit hardware-configuration to set neededForBoot=true; at /persistent
• nix flake lock --update-input asahi-firmware
• sudo nixos-rebuild boot --impure
• reboot

To apply changes:

sudo nixos-rebuild switch --impure
