The disk image was ~6.2 GiB of closure, largely desktop/multimedia baggage a
single-purpose Electron kiosk never uses. Cut the clearly-unused stacks:
- services.speechd off → drops speech-dispatcher's espeak-ng + mbrola voices
(~1 GB text-to-speech). An ATM does not talk.
- v4l-utils built withGUI=false → drops the entire Qt6 stack (~0.5 GB) that only
backed the qv4l2 GUI; the v4l2-ctl CLI we actually use for the camera stays.
- documentation off (man/info/NixOS manual) — nobody reads them on a kiosk.
Closure 6.2 → 5.0 GiB. The remaining bulk is electron's own runtime (gtk4/
gstreamer/pipewire, unavoidable), mesa+llvm (GPU), and linux-firmware — those
need heavier / riskier work to touch. Distribute the image as .img.zst.

Was: weekly, no persistence. Problem: 15GB eMMC + ~7GB closure means
cross-release upgrades are always tight. Weekly cadence stacked up to
a week of generations under the 04:00 auto-upgrade. Persistent=false
also meant a Sintra powered off at 03:30 skipped GC until next week.
Now runs daily at 03:30, 30 min before the 04:00 nixos-upgrade so each
upgrade attempt gets the freshest headroom. 7d retention unchanged.
This is a periodic-cleanup fix only — cross-release in-place upgrades
on 15GB eMMC will still hit the disk-full wall (caught 2026-05-26 on
24.05 → 24.11). Reflash remains the answer there.

System-level half of the lamassu → bitspire rebrand the rest of dev
already did at the path / service / package layers. Touches user/group
declarations, every systemd `User=` block, the udev rules filename, all
chown calls in flake.nix + live.nix, the displayManager autoLogin user,
the trusted-users nix entry, provision-atm.sh's ATM_USER, plus README +
CLAUDE.md doc references.
In-place migration for the Sintra dev unit (which auto-pulls dev at
04:00) lives in `system.activationScripts.bitspire-user-migration` and:
- copies `/home/lamassu/.ssh/authorized_keys` → `/home/bitspire/` once,
so SSH access survives the rename
- recursively chowns `/var/lib/bitspire` to the new bitspire UID on
every boot — cheap no-op once done, but covers the case where the
data dir was written by the now-removed lamassu UID
- leaves `/home/lamassu/` in place as evidence; operator can `rm -rf`
after confirming bitspire login works
Recovery path if the migration breaks SSH access: root key is still in
configuration.nix:142-144 (padreug@gizmo), so ssh root@<host> works.

Five-file coordinated rename to give the dev-branch deploy a clean
`bitspire` namespace at the NixOS level:
deploy/nixos/lamassu-atm.nix → deploy/nixos/bitspire-atm.nix
- `services.lamassu-atm` → `services.bitspire`
- `systemd.services.lamassu-atm` → `systemd.services.bitspire`
- `/var/lib/lamassu-atm` → `/var/lib/bitspire`
- `/opt/lamassu-atm` → `/opt/bitspire`
- `/etc/lamassu-atm/config.env` → `/etc/bitspire/config.env`
flake.nix
- module import path updated
- `nixosModules.lamassu-atm` → `nixosModules.bitspire`
- `system.activationScripts.lamassu-env` → `bitspire-env`
- all activation-script paths point at /var/lib/bitspire
deploy/nixos/configuration.nix
- `networking.hostName = "lamassu-atm"` → `"bitspire"`
deploy/nixos/live.nix
- module import path updated
- ISO name template: `lamassu-atm-<model>-live.iso` → `bitspire-<model>-live.iso`
- activation-script name updated
deploy/nixos/provision-atm.sh
- data-dir paths: /var/lib/lamassu-atm → /var/lib/bitspire
- systemctl + journalctl unit names updated
DELIBERATELY kept as `lamassu` (for now):
- The `lamassu` UNIX user and group account. Renaming would
require file-ownership migration scripts; the Sintra is a
fresh flash so no existing data, but the internal user
namespace inconsistency is acceptable.
- LP-specific bits in provision-atm.sh (admin token, the
`docker logs lamassu-lightning-pub` extractor) — those
get ripped out in 3c when the script switches to LNbits.
NO migration activation script added — the Sintra flash is fresh,
production batm3/douro stay on `main` and never see this branch.
A future dev→main cutover will need a separate migration story
(rename UNIX user, move /var/lib/lamassu-atm → /var/lib/bitspire,
SSH key relocation, etc.).
Verified:
nix eval .#nixosConfigurations.batm3-installed.config.systemd.services.bitspire.enable
→ true
nix eval .#nixosConfigurations.bitSpire-live-sintra.config.networking.hostName
→ "bitspire"

Move WireGuard IP from shared configuration.nix to per-machine
hardware configs. douro = 10.0.0.4, batm3 = 10.0.0.5.
Previously both machines shared 10.0.0.4 which caused routing
conflicts on the VPS.

Allow key-only root login (PermitRootLogin prohibit-password) and add
authorized SSH key for remote administration.

Configures wg0 interface (10.0.0.4/24) to VPS at 170.75.161.21:51820
for remote SSH access. Opens UDP 51820 in firewall and adds activation
script to ensure key directory permissions.

Cassette inventory was never initialized in SQLite, so
recordTransaction's UPDATE decrements were no-ops against an empty
table. Now the Electron main process seeds cassettes from
VITE_LAMASSU_CASSETTES or the model preset on first boot.
Also adds an atm-transactions CLI script (with --summary, --inventory,
--type, --today, --last, --since filters) and sqlite to the NixOS
system packages.

The option was renamed from services.xserver.displayManager.autoLogin
to services.displayManager.autoLogin.

Add NixOS configuration to build a bootable live USB ISO that runs the
ATM Electron app in kiosk mode on physical hardware (UpBoard). The ISO
boots from squashfs, auto-starts X11/openbox, and launches Electron in
production mode.
Key changes:
- deploy/nixos/live.nix: Live USB module (squashfs+tmpfs, no disk install)
- deploy/nixos/flake.nix: Nix flake with ISO build output
- deploy/nixos/provision-atm.sh: Auto-provision LP credentials via API
- deploy/nixos/build-iso.sh: End-to-end build workflow script
- apps/machine: Fix Electron production mode (ELECTRON_FORCE_PROD),
Vue Router hash mode for file:// protocol, relative asset paths
Build: cd deploy/nixos && bash build-iso.sh
Test: qemu-system-x86_64 -enable-kvm -m 2G -cdrom result/iso/*.iso
