Wifi won't connect on Bullseye! (solution inside) (not clickbait)

desertbot.io adds systemd.restore_state=0 (don't restore) and rfkill.default_state=1 (unblocked) to boot/cmdline.txt (kernel params) and that seems to work. This can be done prior to first boot, eg. by this here script, and will survive to subsequent boots (after fs resize).

Todo:

• get a monitor and investigate whether rfkill state is the true cause

  • if so, send a PR to https://www.raspberrypi.com/documentation/computers/configuration.html#setting-up-a-headless-raspberry-pi to reflect this in upstream docs

Note: You can mount /boot prior to burning the img file to retrieve the original kernel params : mount -o loop,offset=$((8192*512)) 2022-01-28-raspios-bullseye-armhf-lite.img $MNT_DIR (read more here)

Hotfix for the meantime
