# do/don't start, to the serial port (/dev/ttyS0) so it can be read on the VM
# host. Launched as a Hyprland exec-once, so it inherits the Wayland env.

# do/don't start. Runs as liveuser (Hyprland exec-once, so it has the Wayland
# env), and writes the report to the serial port via sudo (the port is
# root-only) so it can be read on the VM host.
