Off topic, I know, but that's incorrect. In fact, for all of my user
desktops, I configure the power button to simply log out all local
sessions. (I also disconnect the reset buttons.) If you tell systemd
not to handle the power button it passes control to acpid, and you can
tell acpid to run any executable you like.
Of course the long-press of the power button is done in hardware and
can't be controlled by the OS.
