Nikita's NixOS Dotfiles

I like simple and reliable configs, preferrably 1 file for each software.

Why I'm using Nix:

• Things never break, and if they do its easy to roll back
• Easy to build software from source with flakes
• Using a programming language for configuration is really powerful

Installation

WiFi Connection

Find out SSID and INTERFACE with:

iwlist scan | grep ESSID && ip link

Generate WiFi configuration and connect to wifi:

wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant.conf
wpa_supplicant -B -i INTERFACE -c /etc/wpa_supplicant.conf

Partition drives:

sgdisk -Z -n1:0:+512M -t1:ef02 -c1:boot \
       -N2 -t2:8309 -c2:root /dev/sdX

Luks setup:

cryptsetup luksFormat /dev/disk/by-partlabel/root
cryptsetup luksOpen /dev/disk/by-partlabel/root cryptroot

Set up logical volumes:

pvcreate /dev/mapper/cryptroot
vgcreate vg /dev/mapper/cryptroot
lvcreate -L 8G -n swap vg
lvcreate -l '100%FREE' -n root vg

Format partitions:

mkfs.fat /dev/disk/by-partlabel/boot
mkfs.ext4 -L root /dev/vg/root
mkswap -L swap /dev/vg/swap

Install nixOS

mount /dev/vg/root /mnt
mkdir /mnt/boot
mount /dev/disk/by-partlabel/boot /mnt/boot
swapon /dev/vg/swap

Copy wpa_supplicant configuration:

cp /etc/wpa_supplicant.conf /mnt/etc/wpa_supplicant.conf

Final steps

nix-shell -p git
git clone https://github.com/nikitarevenco/dotfiles.git \
          /mnt/etc/nixos
nixos-generate-config --root /mnt --show-hardware-config \
            > /mnt/etc/nix/hardware.nix
nixos-install
reboot
