systemd to wait for command to complete before restart/shutdown or killing other processes

  • 772

When I'm initiating "reboot" or "poweroff", systemd is killing all the processes, but I need it to wait for one particular application to finish before stopping other services.

Actually, I want Virtualbox vm clean shutdown/savestate. Have no problem of doing it manually with this service file, but during the shutdown - processes are killed. How can I control it?

I've read docs, but didn't find clear solution for this kind of dependency.
