Well... it won't be dropped anytime soon, but I recall Kern stating 
that he won't touch that code anymore, so once he needs to rework the 
code related to automatic volume labeling, it might be gone.

I couldn't say how likely that is, though - might be tomorrow, or in 
ten years.

That requirement, by the way, is not very problematic. The sample 
given in the manual should almost work out of the box, and python is 
easier to learn than Baculas variable substitution language :-)

Anyway - I'm operating Bacula installations using the LabelFormat 
option as well, and those work correctly. But then, these 
installations haven't labeled a volume for more than a year now, as 
their pools have reached their maximum number of volumes by now. It 
might be that there is a bug somewhere, which noone noticed yet.

You could try to set up a test pool and job, where you limit the 
volumes to, say, 10MB, use the most simple form of LabelFormat, i.e. 
"Label-" or something, and assign a newly created storage device to it.

Then, run a job, preferrably with debug output enabled, and see what 
happens.

That should eliminate the chance that some misconfiguration crept into 
your catalog, and it should give a good set of debug files to analyze 
quickly.
