# 2021-07-27 explanation from @jvonau: The 3 BELOW (iw, rfkill, wireless-tools)
# are provided by RasPiOS.  Ubuntu|Debian on the other hand are hit or miss:
# desktops might have some/all 3 preinstalled, while servers tend not to have
# these present at all, but are needed to be installed if you want to take full
# advantage of WiFi on Ubuntu and friends.
