Thank you John for the prompt answer. However this seems not to fix the 
entire issue. The tape is not ejected.....
I have no idea how to do this from within Bacula and obviously I cannot 
use 'mt -f /dev/nst0 eject' from a script as Bacula still locks the device.
After some google-ing I found a workaround that suggests maintaining my 
original script, but adding a mount command at the end which would mount 
an empty drive and thus producing an error but with the side effect that 
Bacula has control over the tapedrive again.
Is there a more elegant way?
