then sudo service vdr stop sudo umount /video sudo udisksctl power-off -b /dev/sda fi The first step appears to terminate the shell script, because the shell is a subprocess of VDR. So, the storage will remain mounted and powered on. I guess that we need to launch a separate "vdr-shutdown" service that would take care of the remaining steps. Has someone already implemented something like this?
Maybe you can prevent that by backgrounding and setting some bash trap's on SIGINT or SIGKILL. Other methods to decouple a process so it runs separated, would be 'nohup' or the old 'at now' trick. However, I'd say the most clean way is to include the unmount and udiskctrl into the vdr shutdown itself, so these commands run within the vdr service after the vdr process stops. That way you just have to fire the service stop and are done. From a quick look into documentation, you can just not wait for the stop to complete: systemctl stop vdr.service --no-block Or if you want to go full systemd, you can probably do a service that does the mount/unmount/poweroff on start/stop, and then add that as requirement to the vdr service.
