Separate user identity (data) from the reusable modules, and let a host declare any number of users instead of exactly one. - users/registry.nix: per-user identity (name, email, groups, authorized and signing keys) as the single source of identity; no user data is hardcoded in the modules. - mkHost takes a `users` set keyed by username; per-user identity is injected into each home config via the `identity` module arg (extraSpecialArgs is per-host, so it cannot carry per-user data). - modules/users.nix builds accounts from the registry; modules/ssh.nix no longer defines authorized keys (the registry owns them); home/git.nix and home/desktop.nix read `identity`; users/emmathorpe/work.nix drops its now-redundant git identity override. - Restructure the tree: users/, home/, modules/, hosts/, lib/ replace the former lyrathorpe/ and system/ layout. - Add standalone homeConfigurations (the portable subset: shell, git, editor, claude) and an exported homeModules output for use on machines not managed by this flake, or as an input to other flakes. Behaviour-preserving for existing hosts: lyrathorpe-mbp and emmathorpe-edaas evaluate to identical derivations; lyrathorpe-t400, lyrathorpe-macpro31 and lyrathorpe-rpi5 differ only by de-duplicating a repeated authorized_keys entry. Fixes the SSH authorized-key leak (one user's key was applied to every account), the hardcoded default git identity, and the hardcoded EDaaS linger setting.
Mac Pro 3,1 (Early 2008) — install notes
Flake host: lyrathorpe-macpro31. Desktop (portable = false, imports
../../modules/desktop.nix). Files: configuration.nix,
hardware-configuration.nix.
Hardware configuration
hardware-configuration.nix here is the real config generated by
nixos-generate-config on the machine. Root is an LVM logical volume
(/dev/mapper/MacPro-Root, ext4); the ESP (vfat) and swap are referenced by
UUID. The initrd carries dm-snapshot for the LVM root. Regenerate and commit
if the disk layout changes.
Bootloader
The Mac Pro 3,1 has 64-bit EFI, so it uses systemd-boot (no GRUB/CSM
shim). canTouchEfiVariables = false because Apple's firmware does not reliably
accept efibootmgr NVRAM writes.
Apple-EFI quirk: if the firmware boot picker does not show NixOS after install, either
- uncomment
boot.loader.efi.efiInstallAsRemovable = true;inconfiguration.nix(installs the fallback\EFI\BOOT\BOOTX64.EFI), and/or - "bless" the ESP from macOS.
Partition the disk GPT with an ESP (vfat).
Graphics
The stock card varies between units — ATI Radeon HD 2600 XT or NVIDIA GeForce 8800 GT. No proprietary driver is hardcoded; Sway relies on in-tree KMS:
- ATI Radeon HD 2600 XT →
radeon(oramdgpu) KMS - NVIDIA GeForce 8800 GT →
nouveauKMS
These come up automatically. If a card needs forcing, set
services.xserver.videoDrivers and/or add the module to
boot.initrd.kernelModules for early KMS (see the comment in
configuration.nix).
Networking
Wired Ethernet via NetworkManager (from desktop.nix) — the Mac Pro has two
gigabit ports.
Login
Graphical login via a Wayland greeter — greetd running ReGreet inside the
cage kiosk compositor — configured centrally in lyrathorpe/swaywm.nix for
every Sway host (gated on features.swayDesktop.enable). The greeter is forced
to the Dvorak layout to match the console and Sway session. Set the user
password (passwd lyrathorpe) after install, or the greeter cannot
authenticate. Requires working KMS (radeon/nouveau — see Graphics).
