I would like to move my old fashioned start/stop/status init script to systemdIt basically does, start:ifconfig eth0:vip 10.0.0.1/24 upstop:ifconfig eth0:vip downstatus:ifconfig  | grep 'eth0:vip'I have tried to create a systemd service unit:[Service]Type=oneshotRemainAfterExit=yesExecStart=/path/myscript startExecStop=/path/myscript stopRestart=noBut systemctl status doesn't have any way to detect when eth0:vip goes down with a manual ifconfig eth0:vip down.What should I do to have my script be compliant to systemd?
