I tried the rpi-imager tool for the first time to write RPiOS to an SD card. I've always just used
dd and then manually edited the
config files in
boot/. I entered my WiFi information in the GUI and wrote to the SD card, stuck it in and the RPi came online and connected to my network, but I want to know where the rpi-imager GUI writes the WiFi information.
It's not where I expect:
$ sudo cat /etc/wpa_supplicant/wpa_supplicant.conf
but the Pi is definitely online and connected to my network!
