# NixOS configuration
Current version: *22.05* + flakes
## Create a bootable USB drive
- Download NixOS to `$ISO_PATH`
- insert drive
- `lsblk` -> find out drive name (e.g. `/dev/sdb`) `$DRIVE`
- run (as sudo) `dd bs=4M if=$ISO_PATH of=$DRIVE conv=fdatasync status=progress && sync`
## Actual installation
Roughly this https://qfpl.io/posts/installing-nixos/
- lsblk -> find out disk name (e.g. `/dev/sda`) `$DISK`
- `gdisk $DISK`
- `p` (print)
- `d` (delete)
- `n` (new)
- number=1, begin=default, end=`+1G`, hex code=`ef00` (not needed if dual boot) (`$BOOT` from now on, or `/dev/sda1` etc)
- number=2, begin=default, end=default, hex code=`8e00` (`$MAIN` from now on)
- `w` (write)
- encryption
- `cryptsetup luksFormat $MAIN`
- `cryptsetup luksOpen $MAIN nixos-enc`
- `pvcreate /dev/mapper/nixos-enc`
- `vgcreate nixos-vg /dev/mapper/nixos-enc`
- `lvcreate -L -n swap nixos-vg`
- `lvcreate -l 100%FREE -n root nixos-vg`
- create fs
- `mkfs.vfat -n boot $BOOT` (not needed if dual boot)
- `mkfs.ext4 -L nixos /dev/nixos-vg/root`
- `mkswap -L swap /dev/nixos-vg/swap`
- `swapon /dev/nixos-vg/swap`
- mount
- `mount /dev/nixos-vg/root /mnt`
- `mkdir /mnt/boot`
- `mount $BOOT /mnt/boot`
- generate config
- `nixos-generate-config --root /mnt`
- add stuff to config
- if dual boot check out https://nixos.wiki/wiki/Dual_Booting_NixOS_and_Windows
dual boot:
```nix
boot.loader.grub.enable = true;
boot.loader.grub.version = 2;
boot.loader.grub.device = "/dev/sda";
boot.loader.grub.useOSProber = true;
```
required:
```nix
boot.initrd.luks.devices = {
root = {
device = "$MAIN";
preLVM = true;
};
};
boot.loader.systemd-boot.enable = true;
networking.networkmanager.enable = true;
users.extraUsers.alex = {
createHome = true;
extraGroups = ["wheel" "video" "audio" "disk" "networkmanager"];
group = "users";
home = "/home/alex";
isNormalUser = true;
uid = 1000;
};
```
- nixos go brrrr
- `nixos-install`
- `reboot`
to have a DM after first boot:
```nix
services.xserver = {
enable = true;
displayManager = {
gdm = {
enable = true;
wayland = false;
};
};
desktopManager.plasma5.enable = true; # or xfce or whatever
# or
# windowManager.xmonad.enable = true;
# to be able to mount an external drive to get secrets etc. for cloning from gh
boot.supportedFilesystems = [ "ntfs" ];
};
```
## Useful
- connect to internet from nmcli
- find out interface: `nmcli d` (`$IF`)
- enable interface: `nmcli r wifi on`
- search networks: `nmcli d wifi list`
- connect: `nmcli d wifi connect $(B)SSID password $PASSWORD`
## Post-installation instructions
(`$CONFIG` is the location of this repo)
- `git clone [email protected]:alexpeits/nixos-config.git $CONFIG`
- `sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware`
- `sudo nix-channel --update`
- change your name to alex because it's hardcoded in the configurations
- `sudo mkdir -m 0755 -p /nix/var/nix/{profiles,gcroots}/per-user/alex` (for `home-manager`)
- Update flake.nix with new machine (preferably name = hostname)
- `sudo nixos-rebuild switch --flake '/path/to/nixos/config#`
