Hi! 👋

This repository contains the definition of my machines using nix.

Important

Disclaimer: This is my personal configuration that works for me. I hope this helps you!

If you are new to dotfiles in general, I suggest a bare git solution to start with.

Hosts

Hostname	CPU	RAM	Primary GPU	Secondary GPU	OS
`laptop`	AMD Ryzen™ 7 7840HS	32GB	AMD Radeon™ 780M	NVIDIA® GeForce RTX™ 4060 8GB	❄️
`work-macos`	Apple M2 Pro 8-core CPU	16GB	Apple M2 Pro 10-core GPU		🍏

Flake Outputs

Listing only the most relevant outputs. See the source-code for more details.

Packages

dotfiles: Wrapper around nix/nixos-rebuild operations.
project: Custom fzf integration to quickly open projects within PROJ_DIR or XDG_DOCUMENTS_DIR. Includes fish widget.
fzf-rg: fzf + ripgrep. Includes fish widget.
fzf-fd: fzf + fd. Includes fish widget.
preview: Custom barebones terminal file previewer to together with the other widgets. I really like yazi previewer but can't use it in isolation.

Tryout using:

nix run github:bphenriques/dotfiles#{package}

Home Manager modules

programs-dotfiles: Accompanies the dotfiles package.
programs-project: Accompanies the project package.
programs-fzf-fd: Accompanies the fzf-fd package.
programs-fzf-rg: Accompanies the fzf-rg package.
xdg-mime-apps: Custom xdg-mime-apps module to abstract setting the common application for typical common text/images/audio/video mimes.

NixOS modules

proton-run: proton-ge-custom runner using a global prefix for ad-hoc executions.
services-input-solaar: Solaar service.
boot-theme: Custom boot configuration including plymouth-themes, settings to hide logs, and an OLED friendly Grub2 theme.

Nix Darwin modules

system-screencapture: Ensures the the screencapture directory exists.
system-desktop: Sets a wallpaper on all desktops. Not perfect but good enough for me.

Install

NixOS

Create host

Create a bootable USB installer:

sudo fdisk -l
sudo dd bs=4M if=<ISO> of=<PEN_DRIVE> status=progress oflag=sync

On the target machine, boot onto the NixOS's installer, set nixos's password using passwd and obtain its IP.

On the source machine, create a new host with the initial hardware configuration and disko set:

HOST=new-host
TARGET_IP=192.168.68.58
ssh nixos@$TARGET_IP -- nixos-generate-config --no-filesystems --root /mnt --show-hardware-config > hosts/$HOST/hardware-configuration.nix

Install remotely

Boot onto the NixOS installer (see previous section).

On a NixOS source machine run:

HOST=new-host
TARGET_IP=192.168.68.58
./bin/nixos-remote-install.sh $HOST nixos@$TARGET_IP

On the target machine, run the following after the installation:

HOST=laptop
BITWARDEN_EMAIL=...
nix run --extra-experimental-features 'nix-command flakes' "github:bphenriques/dotfiles#dotfiles-install" -- $HOST $BITWARDEN_EMAIL

Darwin

Install nix.

Boostrap:

nix run --extra-experimental-features 'nix-command flakes' github:bphenriques/dotfiles#darwin-install

Setup the dotfiles repository:

HOST=work-macos
BITWARDEN_EMAIL=...
nix run --extra-experimental-features 'nix-command flakes' "github:bphenriques/dotfiles#dotfiles-install" -- laptop $BITWARDEN_EMAIL

Apply:

"$HOME"/.dotfiles/packages/dotfiles/dotfiles.sh sync

Reboot!

Secrets

Secrets: sops-nix.
Private information: private flake under bphenriques/dotfiles-private.

Adding new hosts requires:

Generate key pair using: nix-shell -p age --command "age-keygen".
Export the private key to $HOME/.config/sops/age/keys.txt and upload to Bitwarden using the format sops-age-key-$HOST-$USER with a private field inside.
Add new host to .sops.yaml using the public key to .sops.yaml and the correct path_regex.
