Disable wakeup triggers on Debian

Here’s a little systemd unit and script to disable ACPI-registered wakeup sources automatically at startup. It’s quick and dirty, but has the advantage of being set-and-forget. No more waking up your computer by accident with your mouse, keyboard or otherwise. The power button still works, though.

The systemd unit calls this bit of code, which disables all wakeup triggers associated with currently connected peripherals:

for d in $(cat /proc/acpi/wakeup | grep enabled | awk '{print $1}')
do
	echo $d > /proc/acpi/wakeup
done

Instructions to install are available in the Git repo. Tested on Debian 12 and 13, but it probably works on most distros.
