[IDEA] Use Raspberry Pi Imager to configure WLAN country, time zone & keyboard layout

[TheOldPresbyope]

I verified the code in worker.php that extracts the country code from pi-imager generated wpa_supplicant and then updates cfg_network table works correctly.

What doesn't seem right is the wpa_supplicant file generated by the Pi Imager. It has country = US even though /boot/firstrun.sh shows country = GB which I specified in the imager.

Here's my test

1. Prep image using Pi-Imager 1.8.4
2. Set WiFi country to something other than US
3. Write the image
4. Insert USB-uSD dongle into a moOde Pi

# Save firstrun.sh file and examine it, verify country code
5. sudo cp /media/boot/firstrun.sh ./

# Add debug line to worker.php
6. sudo nano /media/rootfs/var/www/daemon/worker.php and add the bolded line 

// Pi Imager: Import SSID/PSK/Country
if (file_exists('/etc/wpa_supplicant/wpa_supplicant.conf')) {
    $moodeHeader = sysCmd('cat /etc/wpa_supplicant/wpa_supplicant.conf 2>&1 | grep "This file is automatically generated"');
    sysCmd('cp /etc/wpa_supplicant/wpa_supplicant.conf /home/pi/');

7. Boot a Pi with the modified uSD card
8. SSH

# Examine country code
9. sudo cat ./wpa_supplicant.conf

It gets weirder---at least to me.

With vanilla (e.g., no moOde) Bullseye 64-bit Lite flashed with Imager options set for Germany, wpa_supplicant.conf ends up with no country code line at all.

Similarly with vanilla Bookworm 64-bit Lite, where the connection info is stored in /etc/NetworkManager/system-connections, I find no country code associated with the WiFi subsystem.

I suppose in managed (aka infrastructure) mode this perhaps doesn't matter because it's the detectable APs which dictate which frequencies are acceptable for connection. Still, I don't understand the inner workings well enough to make any definitive statement.

And in neither case is the locale properly set. In the bookworm test I'm running ATM I get (because RaspiOS comes configured for the UK)

Code:

pi@bookworm-test:~ $ locale
LANG=en_GB.UTF-8
LANGUAGE=
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=

yet the time zone is Europe/Berlin and the default keyboard settings include XKBLAYOUT="de" due to  firstrun.sh.

PS - For what it's worth, I'm running Imager v1.8.4 on a Linux laptop.
