[CentOS] Running script before reboot or shutdown

Hi all,

I am trying to configure a script as a systemd service to run first when a shutdown or reboot is called. This script execute some scp commands to copy some files to other machines. My actual defined systemd’s file is:

[Unit] Description=Remote copy some files before reboot/shutdown Before=poweroff.target halt.target shutdown.target reboot.target DefaultDependencies=no

[Service] Type=simple ExecStart=/bin/true ExecStop=/usr/local/bin/remote_copy RemainAfterExit=yes

[Install] WantedBy=multi-user.target

But it doesn’t work. “remote_copy” is working when it is executed from root shell. I am using CentOS-8 fully patched release.

Any idea what am I doing wrong?
