Enhance first-boot setup by adding dark theme configuration for user pi and enabling rpi-eeprom-update on CM4 for boot order management. Update documentation to reflect these changes and improve logging for boot order settings. Implement a one-shot service to ensure boot order is set after reboot on CM4.

12. **CM4 EEPROM enable** — On CM4, `rpi-eeprom-update` is disabled by default. First-boot enables it by: adding `RPI_EEPROM_USE_FLASHROM=1` and `CM4_ENABLE_RPI_EEPROM_UPDATE=1` to `/etc/default/rpi-eeprom-update`; adding a `[cm4]` block to `config.txt` with `dtparam=spi=on`, `dtoverlay=audremap`, `dtoverlay=spi-gpio40-45`. After reboot, `rpi-eeprom-update -l` works and boot order can be set.

13. **Boot order** — If `rpi-eeprom-config` is available, set `BOOT_ORDER=0x21` (network first, then eMMC/SD). On CM4 first boot this may be skipped (EEPROM not yet enabled); a one-shot systemd service runs after reboot to set boot order once.

## Dark theme
|
||||
|
||||
First-boot sets a dark GTK theme for user **pi** via **`~/.config/gtk-3.0/settings.ini`** with **`gtk-application-prefer-dark-theme=1`** and **`gtk-theme-name=PiXnoir`**. On older images use **Adwaita-dark** if PiXnoir is missing.
|
||||
|
||||
## CM4: enable rpi-eeprom-update (for boot order)
|
||||
|
||||
On **CM4**, first-boot enables `rpi-eeprom-update` by: (1) **`/etc/default/rpi-eeprom-update`**: **`RPI_EEPROM_USE_FLASHROM=1`**, **`CM4_ENABLE_RPI_EEPROM_UPDATE=1`**; (2) **config.txt** **`[cm4]`** block: **`dtparam=spi=on`**, **`dtoverlay=audremap`**, **`dtoverlay=spi-gpio40-45`**. After reboot, **`rpi-eeprom-update -l`** works. See: [usbboot](https://github.com/raspberrypi/usbboot/blob/master/Readme.md).
|
||||
|
||||
## Boot order (network first, then eMMC/SD)
|
||||
|
||||
If **`rpi-eeprom-config`** and **`rpi-eeprom-update`** are present (Pi 4/CM4), the script sets the EEPROM **`BOOT_ORDER=0x21`**: try **network** first (0x2), then **SD/eMMC** (0x1). This allows future network boot or re-provisioning (e.g. PXE or USB gadget) before falling back to local storage. The EEPROM update is scheduled for the next reboot; no second reboot is required. If “Could not read current EEPROM config” appears, run `sudo rpi-eeprom-update -l` on the device to see if a firmware file is listed; you can set boot order manually with `rpi-eeprom-config` if needed. If the tools are not available, the step is skipped.
