Minor additions to Bookworm vs Bullseye guide

[samveen]

• Quick Wifi connection setup with nmcli:

  nmcli con add type wifi con-name FSL ssid FSL wifi-sec.key-mgmt wpa-psk wifi-sec.psk MixedFruitS@l@d save yes
  

• Possibly a new section for Firmware management differences (i.e. location of config.txt, cmdline.txt etc.):

  Firmware size/mountpoint differences
  Bullseye: First partition of SD containing the firmware is mounted on `/boot` , sized at 256M
  Bookworm: First partition of SD containing the firmware is mounted on `/boot/firmware` sized at 512M
  

• Headless logging optimization across all Pi's and OS version:

  For purely headless setups, the order of the 2 console options in the cmdline.txt is very important: the last of the options should be the serial console, so that all boot messages are redirected to serial console. The default setup causes the messages to be directed to /dev/tty1: Code:

  ... console=tty1 console=ttyAMA0,115200 ...
  

• A way of combining venv activation and python invocation into single shell command - helps when using multiple venv for tasks without affecting the parent shell environment:

  bash -c "source $VENV_ROOT/bin/activate ; python $PYTHON_SCRIPT"
  

  where the example of VENV_ROOT is /home/pi/.venv/ and example of 'PYTHON_SCRIPT is '/home/pi/SomeProgram.py
