# 2023-04-24 PR #3542 / PR #3549 context:
# "systemd-network" "RasPiOS" have files with the client wifi info within them,
# those can be parsed for the ssid without needing the related service running
# first.
# "Netplan systemd" "NetworkManager" need to be running to be able to parse for
# the ssid, from the generated config file for "Netplan systemd" and from the
# running environment for "NetworkManager".
# "iiab-wifi-test.service" acts as a bit of a traffic cop keeping the ordering
# of the services more deterministic when active and tries to catch a channel
# mismatch between client wifi's current setting and what is contained within
# hostapd.conf early in the boot process.
