dotfiles

Setup

Clone the repo and link

git clone https://github.com/mantas6/dots.git "$HOME/.dots"
cd "$HOME/.dots"
./bin/dot/stw

If stow fails, remove conflicting files (preferably to trash) and run again. Pay close attention to the output to make sure that the links that it creates make sense.

Create NixOS ISO

nix run nixpkgs#nixos-generators -- --format iso --flake '#iso'

Install NixOS

    --generate-hardware-config nixos-generate-config nix/hosts/__host__/hardware.nix \
    --target-host "root@__host__"

Encrypted setup:

nix run nixpkgs#nixos-anywhere -- \
    --flake ".#__host__" \
    --disk-encryption-keys /tmp/secret.key <(pass "hosts/__host__") \
    --generate-hardware-config nixos-generate-config nix/hosts/"__host__"/hardware.nix \
    --target-host "root@__host__"

Deploy NixOS on the network

nixos-rebuild --flake .#__host__ --target-host root@__host__ switch
