# CONFUSING BUT FYI: Steps below run *strictly sequentially* when this script
# (/usr/local/sbin/iiab-netwarn) is run on boot, triggered by either autostart:
# https://specifications.freedesktop.org/autostart-spec/autostart-spec-latest.html
# ...or by Wayland compositor Wayfire's ~/.config/wayfire.ini for RasPiOS 12+:
# https://github.com/WayfireWM/wayfire/wiki/Configuration#autostart
#
# This allows return codes ($rc) 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 manually after boot from a regular graphical desktop session -- so
# make sure to test (either kind of) "autostart" during actual OS boot-up!
