# CONFUSING BUT FYI: Commands below run *strictly sequentially* when this
# script (/usr/local/sbin/netwarn) is invoked by autostart during OS boot.
# This allows return codes to be meaningful, at each successive step.
# (As of July 2022, this is tested to work well with Ubuntu Mate and "Raspberry
# Pi OS with desktop" on Raspberry Pi 4!)
#
# IN CONTRAST: return codes below are NOT MEANINGFUL when this script is
# invoked from a regularly graphical desktop session -- so make sure to test
# during an actual OS boot-up, with autostart!
