feature request: snapshot before shutdown

[rhjdvsgsgks]

i have already tried add a systemd unit to create a snapshot before shutdown.target, unfortunately not working because dbus already in "shutting down" state, use snapper create will got a Failure (org.freedesktop.systemd1.ShuttingDown). so it would be great if snapshot can be created on "server side" received "shutdown signal" from systemd.

snapperd is only running on demand for a short time when needed. So in general it is not running when the system is doing a shutdown.

you can create the script shutdown_script.sh and move it in shutdown-directory (e.g KDE .config/plasma-workspace/shutdown/)

!#/usr/bin/env bash

# you can create snapshot, what you want
snapper ....
sleep 5 # wait for 5 sec.
