Just opening an issue so this one doesn't get forgotten. Since at least 2016 the os has supported hands-off configuring of wifi via dropping a wpa_supplicant.conf file into the boot partition in the image. This was removed in the bookworm-based os but this longstanding (and very very helpful) functionality has not been replaced with some other equivalent feature.

For those of us who (a) do not use rpi-imager at all and (b) do a lot of burning of SD cards for headless raspi-lite systems, it is very important to give us an alternate way to seed our images with the wifi configuration. Please make it so in the very near future.

suggestion - if we could have a firstboot file where we simply wrote the nmcli options needed to set up wifi, you could do something like "nmcli `cat /boot/firmware/nmcli.options`" or the like to exec nmcli for us based on data that was there, if that file was present. Or just do a cp of a NetworkManager/ tree from the boot partition into place under /etc. Or any other mechanism you want. It's not necessary to go full cloud-init but I see rpi-imager uses that. 'Any' mechanism that works is fine and much better than the current 'no' mechanism in the 10-10-2023 os. Thanks.
