Made with Doom Emacs NixOS Unstable

Hey, you. You're finally awake. You were trying to configure your OS declaratively, right? Walked right into that NixOS ambush, same as us, and those dotfiles over there.

Disclaimer: This is not a community framework or distribution. It's a private configuration and an ongoing experiment to feel out NixOS. I make no guarantees that it will work out of the box for anyone but myself. It may also change drastically and without warning.

Until I can bend spoons with my nix-fu, please don't treat me like an authority or expert in the NixOS space. Seek help on the NixOS discourse instead.
Shell: zsh + zgenom
DM: lightdm + lightdm-mini-greeter
WM: bspwm + polybar
Editor: Doom Emacs
Terminal: st
Launcher: rofi
Browser: firefox
GTK Theme: Ant Dracula

Quick start

  1. Acquire NixOS 21.11 or newer:

    # Yoink nixos-unstable
wget -O nixos.iso https://channels.nixos.org/nixos-unstable/latest-nixos-minimal-x86_64-linux.iso

# Write it to a flash drive
cp nixos.iso /dev/sdX

  2. Boot into the installer.

  3. Switch to root user: sudo su -

  4. Do your partitions and mount your root to /mnt (for example).

  5. Install these dotfiles:

    nix-shell -p git nixFlakes

# Set HOST to the desired hostname of this system
HOST=...
# Set USER to your desired username (defaults to hlissner)
USER=...

git clone https://github.com/hlissner/dotfiles /etc/dotfiles
cd /etc/dotfiles

# Create a host config in `hosts/` and add it to the repo:
mkdir -p hosts/$HOST
nixos-generate-config --root /mnt --dir /etc/dotfiles/hosts/$HOST
rm -f hosts/$HOST/configuration.nix
cp hosts/kuro/default.nix hosts/$HOST/default.nix
vim hosts/$HOST/default.nix  # configure this for your system; don't use it verbatim!
git add hosts/$HOST

# Install nixOS
USER=$USER nixos-install --root /mnt --impure --flake .#$HOST

# If you get 'unrecognized option: --impure', replace '--impure' with 
# `--option pure-eval no`.

# Then move the dotfiles to the mounted drive!
mv /etc/dotfiles /mnt/etc/dotfiles

  6. Then reboot and you're good to go!

⚠️ Don't forget to change your root and $USER passwords! They are set to nixos by default.
