I just flashed the latest RPi OS Lite image (64 bit) Bullseye and loaded onto a RPi 4B (4GB) using the RPI imager. Released 2022-04-04
When I booted the Pi, I checked its lsb_release -a and I realised, the distributor ID has been changed. Since my Ansible playbook checks LSB release ID, it's currently erroring out.
While I can change my code, I wonder why the distributor ID is not Raspbian anymore.
