NixOS Installation

Some assumptions here about source device so keep that in mind!

Partitioning

Partition layout should look a little something like this.

NAME              MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
nvme0n1           259:0    0 931.5G  0 disk
├─nvme0n1p1       259:1    0   300M  0 part  /boot/efi
└─nvme0n1p2       259:2    0 931.2G  0 part
  ├─sysvg-nixboot 254:0    0     1G  0 lvm   /boot
  ├─sysvg-nix     254:1    0   500G  0 lvm
  │ └─nixos       254:3    0   500G  0 crypt /
  └─sysvg-swap    254:2    0    15G  0 lvm   [SWAP]

Second partition (nvme0n1p2) uses LVM.

Root partition needs to be encrypted ahead of time.

Installation

Mount the target partitions as follows:

• / -> /mnt/
• /boot -> /mnt/boot
• /boot/efi -> /mnt/boot/efi

Copy configuration.nix from the nix folder in this repo.

Note: Consider running nixos-generate-config first to see what the suggested config is

Run installation

nixos-install

Config

Cloning repo

Clone the repo.

mkdir ~/dev
cd ~/dev
git clone git@github.com:andyrichardson/dotfiles.git
git update-index --skip-worktree nix/config/secrets.nix

Configuring secrets

Make sure to populate secrets in nix/config/secrets.nix (maybe check 1password for values)

Linking nix config

Making a system link to the repo folder.

Note: Consider backing up /etc/nixos first

sudo rm -r /etc/nixos
cd ~/dotfiles
sudo ln -s `pwd` /etc/nixos

Install all the things (first run will take a while)

sudo nixos-rebuild switch

SSH keys

Source SSH keys from 1Password (or wherever you've stored them) and copy them to the ~/.ssh folder

chmod 700 ~/.ssh
chmod 644 ~/.ssh/id_rsa.pub
chmod 600 ~/.ssh/id_rsa
eval "$(ssh-agent -s)"
