Derives from the data dir path, so it resolves to the root mount (a no-op) when the data dir lives on the SD card. 2026-08-02T00:24:23Z Luke Hoersten luke@hoersten.org 2026-08-02T00:24:23Z urn:sha1:254577c537e20dbd2e365c63773e2010f3c8374d - create spi/gpio groups and udev device rules (Raspberry Pi OS ships them, Ubuntu does not) - hardware CS via spidev (cs_pin -1); a manual cs_pin on a kernel-owned CE line fails EBUSY - align RAK6421 pin maps with upstream's hardware catalog: en_pins for the FEM enables, gpiod backend on chip 0 (catalog says chip 1, wrong for Pi 4) - us RF preset is now MeshCore USA/Canada (Recommended): 910.525 / SF7 / BW62.5 / CR5 - set storage.storage_dir; omit mqtt_brokers entirely (any key enables the MQTT pusher) - fetch radio-settings/radio-presets json into the data dir (pip omits them and the web setup wizard's hardware step is empty without them) - config deployed 0660 with a vaultable repeater.security block so the daemon can persist credentials and re-templates no longer wipe them - sudoers rule so the web UI can restart the service after config changes 2026-07-26T15:36:29Z Luke Hoersten luke@hoersten.org 2026-07-26T15:36:29Z urn:sha1:38323823b85b2ae8deef788a0f49e36c789c12f4 Deploys the openHop MeshCore repeater on a Raspberry Pi with a RAK6421 WisMesh Pi HAT: installs the daemon into a venv from a versioned git tag, templates config.yaml and a systemd unit, and loads board pin maps and RF region presets by name from vars/. identity_file is configurable and defaults to null (daemon generates its own keypair).
