Opening a terminal (foot) execs `tmux new-session -A -s main`, so every new terminal lands in the multiplexer; panes run a plain non-login zsh. Guarded to interactive, not-already-in-tmux, not-SSH, not-VS-Code, tmux-present -- preventing re-exec loops, hijacked scp/ssh shells, and lockout. Lives in the graphical desktop layer, so the WSL work box keeps a plain shell. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
nixfiles
NixOS / nix-darwin / home-manager configuration for all hosts, built from a single flake.
Hosts
Defined in the host table in flake.nix:
| Configuration | System | Machine |
|---|---|---|
lyrathorpe-mbp |
aarch64-linux |
MacBook Pro (Apple Silicon, Asahi) |
lyrathorpe-t400 |
x86_64-linux |
ThinkPad T400 — install notes |
lyrathorpe-macpro31 |
x86_64-linux |
Mac Pro 3,1, desktop — install notes |
emmathorpe-edaas |
x86_64-linux |
Work WSL box (NixOS-WSL) |
lyrathorpe-mac |
aarch64-darwin |
macOS (nix-darwin) |
Shared layers: lyrathorpe/home (home-manager: shell, git, editor),
system/modules/common-nixos.nix (all NixOS hosts), and
system/modules/laptop.nix (the physical laptops).
Applying
# NixOS
sudo nixos-rebuild switch --flake .#<configuration>
# Darwin
darwin-rebuild switch --flake .#lyrathorpe-mac
Keybindings
All Sway / tmux / foot / zsh keyboard shortcuts are documented in
lyrathorpe/home/KEYBINDINGS.md.
Login / greeter
Graphical (Sway) hosts log in through a Wayland greeter — greetd running
ReGreet inside the cage kiosk compositor — configured centrally in
lyrathorpe/swaywm.nix, gated on
features.swayDesktop.enable. The greeter is forced to Dvorak to match the
console and Sway session. Hosts with features.swayDesktop.enable = false (the
WSL work box) keep plain TTY login. The target account needs a password
(passwd <user>) before it can log in.
MacBook (Asahi) firmware
The MBP host references system/modules/firmware/ for Apple peripheral
firmware (Wi-Fi/Bluetooth). Those blobs are not redistributable, so the
directory is gitignored and a clean checkout will not build lyrathorpe-mbp
until it is populated out-of-band.
Copy the firmware extracted during the Asahi install (from
/etc/nixos/firmware on the freshly-installed machine, or re-extract per the
Asahi NixOS docs) into
system/modules/firmware/ before rebuilding that host.
CI
.gitea/workflows/ci.yaml gates nixfmt
formatting and evaluates every NixOS and Darwin host configuration on push/PR.
