For some reason this piqued my interest, so I spent a bit of time trying to differentiate between shutdown, reboot, and halt.
According to the systemctl man page, each of these is equivalent to "systemctl start xxx.target", for xxx being one of shutdown, reboot, or halt.
I set up a service with an ExecStop like yours. The script:Unfortunately, the systemctl documentation appears to be incorrect. /usr/local/bin/sdxout shows that none of the targets are active.So, you apparently can't use this technique to figure out whether it's a shutdown, reboot, etc.
But, you could set up a script that you use to do the shutdown, reboot, etc that sets an envar in a file that your "shutdown" script reads to figure out what is going to happen after the shutdown. That should work, but I left that as an exercise for the reader![:roll:]( "Rolling Eyes")
