nix-dots

My declarative NixOS + Home Manager configs for five machines across two architectures. Built with the dendritic pattern via flake-parts + import-tree every file just contributes to the flake, no central import list to maintain.

This setup is highly opinionated toward how I want to run things. If you're building your own, feel free to steal whatever's useful, but unless you agree with all my opinions you probably will need to change a fair bit.

Highlights

• Five hosts, two architectures — three x86_64-linux desktops and two aarch64-linux Apple Silicon laptops, sharing profiles cleanly across both
• Ephemeral root on Onyx, Nyx, Lenix, and Phoenix — tmpfs or wipe-on-boot roots, Disko-managed filesystems, opt-in state via Preservation
• Multi-user hosts — Phoenix and Nyx are shared between Connor and Ewan, each with their own home-manager profile and preservation rules
• Stylix + Catppuccin theming, driven declaratively across every app
• Hyprland, launched through UWSM, with Hyprpanel and Vicinae
• Fully declarative Neovim via nvf
• Lix on main running on all hosts.
• Custom packages (e.g. the Robrix Matrix client) built and exposed via perSystem.packages

Hosts

Host	Owner(s)	Device	Notable bits
onyx	Connor	Desktop (x86_64)	Nvidia, gaming (Steam/Proton/Gamescope), custom PipeWire quantum, ephemeral (tmpfs) root, Disko
nyx	Connor, Ewan	Desktop (x86_64)	Nvidia, gaming, OBS w/ CUDA + DaVinci Resolve, secondary XFS data disk, ephemeral (tmpfs) root
phoenix	Connor, Ewan	Desktop (x86_64)	Mesa/integrated graphics, F2FS root wiped on every boot via a Disko + systemd unit, secondary data disk
lenix	Connor	MacBook (Apple Silicon)	Asahi, ephemeral (tmpfs) root, zswap
escapepod3	Leo	MacBook (Apple Silicon)	Asahi, traditional (non-ephemeral) Btrfs root

Users

User	Hosts
Connor	onyx, nyx, phoenix, lenix
Ewan	nyx, phoenix
Leo	escapepod3

Each user has their own NixOS module (account, groups, preservation rules) and home-manager module (packages, dotfiles, per-host overrides like Hyprland config and wallpaper).
