NixOS, nix-darwin, and Home Manager configurations across personal machines.

Machines

Host	Role	Hardware	Deploy
ryu	Linux desktop	Intel i9-14900KS / RTX 5090 / 64GB DDR5 CL36@6000MT/s	deploy -s .#ryu
tako	Linux server	Intel Xeon E-2236 / 64GB DDR5	deploy -s .#tako
tsuba	Linux server	Raspberry Pi 5 / 8GB	deploy -s .#tsuba
kuro	macOS laptop	Apple M4 Pro MacBook / 24GB	deploy -s .#kuro
shiro	macOS desktop	Apple M4 Mac mini / 16GB	deploy -s .#shiro

Layout

• flake.nix — entry point and device definitions
• nixos/ — per-host NixOS configs (ryu, tako, tsuba)
• darwin/ — per-host nix-darwin configs (kuro, shiro)
• home/ — Home Manager modules (programs/, services/, apps/)
• modules/ — custom modules (nixos/, darwin/, home/)
• secrets/ — SOPS-encrypted secrets
• steamdeck/ — standalone Home Manager config for Steam Deck

Validating

nixos-rebuild build --flake .       # current Linux host
darwin-rebuild build --flake .      # current macOS host
alejandra fmt .                     # format all Nix files

Troubleshooting

See TROUBLESHOOTING.md.

TODO

• Verify Gitea Actions nix copy from shiro to tako still works after dropping gitea-runner from tako's nix.settings.trusted-users. Paths must be signed by cache.shiro-1 (shiro's secret-key-files); unsigned imports or --no-check-sigs will fail for non-trusted users.
