My dotfiles

Based on dotfiles by gsnewmark.

A set of NixOS-based system definitions & configuration files for Emacs (Doom Emacs), Fish shell, Firefox/Tridactyl, mpd/ncmpcpp, ranger file manager, alacritty, zathura, and other tools.

Installation

Preparing encrypted partition

Start with adding boot and root partitions with gdisk /dev/nvme0n1 and then

• o (create new empty partition table)
• n (add partition, start at default, end at +512M, type ef00 EFI)
• n (add partition, start at default and use all remaining space, type 8300 Linux LVM)
• w (write partition table and exit)

Follow it by encrypting the root one:

sudo cryptsetup -y -v luksFormat /dev/nvme0n1p2
sudo cryptsetup open /dev/nvme0n1p2 cryptroot
sudo mkfs.ext4 -L root /dev/mapper/cryptroot
sudo mount /dev/mapper/cryptroot /mnt

And finish by creating a filesystem on the boot partition and mounting it:

sudo mkfs.fat -F32 /dev/nvme0n1p1
sudo mkdir /mnt/boot
sudo mount /dev/nvme0n1p1 /mnt/boot

Installing NixOS

Checkout dotfiles without sub-modules for the initial installation:

sudo nix-env -iA nixos.git
cd /mnt/etc
sudo git clone -b nixos https://github.com/erasmas/dotfiles.git

Generate default config to check the hardware config and adjust the one in the dotfiles:

sudo nixos-generate-config --root /mnt

Install the system:

sudo ./mnt/etc/dotfiles/deploy <voyager>

Post-installation cleanup

Chroot and set password for the created user:

sudo nixos-enter
passwd erasmas

Actually check out dotfiles for the created user and link them to the system's configuration.nix:

cd ~
git clone -b nixos --recursive git@github.com:erasmas/dotfiles.git .dotfiles
cp /etc/dotfiles/hardware-configuration.<host>.nix dotfiles/hosts/<host>/hardware-configuration.nix
sudo rm -rf /etc/dotfiles
sudo ln -s /home/erasmas/.dotfiles /etc/dotfiles

Linking dotfiles

I use GNU Stow to manage the dotfiles:

mkdir -p ~/{bin,.config}
stow --target=/home/erasmas/bin bin
stow --dir=config --target=/home/erasmas browser
stow --dir=config --target=/home/erasmas desktop
stow --dir=config --target=/home/erasmas dev
stow --dir=config --target=/home/erasmas emacs
stow --dir=config --target=/home/erasmas music
stow --dir=config --target=/home/erasmas shell

# TODO fisher

Unlinking dotfiles

To remove a particular configuration module use stow's -D option:

stow --target=/home/erasmas/bin -D bin
stow --dir=config --target=/home/erasmas -D browser
stow --dir=config --target=/home/erasmas -D desktop
stow --dir=config --target=/home/erasmas -D dev
stow --dir=config --target=/home/erasmas -D emacs
stow --dir=config --target=/home/erasmas -D music
stow --dir=config --target=/home/erasmas -D shell
